"Level Up Your JavaScript: Array Methods (Part 2)"

Crosston J — Sat, 09 Aug 2025 07:32:28 +0000

Intro for Part 2 – Array Methods

In the previous post, we explored some essential JavaScript array methods and how they make working with data easier. Today, in Part 2, we’ll continue our journey by learning more powerful methods that can help us manipulate, search, and transform arrays with less code and more efficiency.

1. The concat function

creates a new array by combining two or more arrays.

const a = [1, 2];
const b = [3, 4]; 
const result = a.concat(b); 
console.log(result); // [1, 2, 3, 4]

2. copyWithin()

Copies a set of array elements to a different location within the same array.

const arr = [1, 2, 3, 4, 5];
arr.copyWithin(1, 3);  
console.log(arr); // [1, 4, 5, 4, 5]

3. Array slice()

The slice() method returns a shallow copy of a portion of an array into a new array object, selected from start to end
(end not included).

Note: It does not modify the original array.

let fruits = ["apple", "banana", "mango", "orange"];
let sliced = fruits.slice(1, 3);  
console.log(sliced); // Output: ["banana", "mango"]

** Explanation:**

1 is the start index → it includes the value at index 1 ("banana").
3 is the end index → it excludes the value at index 3 ("orange" is not included).
So the result is from index 1 to 2 → ["banana", "mango"].

4. Array splice()

Adds/removes elements from a specified index. Modifies the original array.

let fruits = ["apple", "banana", "mango", "orange"];
fruits.splice(1, 2, "grape", "kiwi");
console.log(fruits); 
// Output: ["apple", "grape", "kiwi", "orange"]

Explanation:

1 → start index (removal begins from index 1 → "banana")

2 → number of elements to remove ("banana" and "mango")

"grape", "kiwi" → elements to insert at that position

After splice(), the original array is modified. It’s not like slice(), which returns a copy.

5. Array toSpliced()

Like splice() but returns a new array and does not modify the original.


let fruits = ["apple", "banana", "mango", "orange"];
let newFruits = fruits.toSpliced(1, 2, "grape", "kiwi");
console.log(newFruits); 
// Output: ["apple", "grape", "kiwi", "orange"]

console.log(fruits);  
// Output: ["apple", "banana", "mango", "orange"]

Explanation:

Works just like splice() (same arguments: start, deleteCount, and items to insert)
But instead of editing fruits, it returns a new modified array
Original array remains unchanged

toSpliced() is useful when you want to avoid mutating the original array, which is important in functional programming or React state updates.

Conclusion

That’s it for Part 2 of our Array Methods series! With these tools in your coding arsenal, you can handle data like a pro. Keep practicing, because the more you use them, the more natural they’ll feel.

Pick Up The Power Of Array Method (Part 1)

Crosston J — Thu, 31 Jul 2025 02:47:50 +0000

INTRODUCTION :

Arrays play a big role in JavaScript. From storing data to updating it, array methods help us manage and work with values easily.
In this part, we’ll look at the most commonly used array methods — simple to learn, but powerful in real-world coding. Each method is explained clearly, with examples you can try right away.
This guide is great for beginners or anyone who wants to revise the basics.

Let’s get started...

1.length()

Gives back the array's total number of elements.

const arr = [10, 20, 30]; console.log(arr.length);  // 3

2.toString()

creates a string from an array by separating its elements with commas.

const arr = [1, 2, 3]; 
console.log(arr.toString());  // "1,2,3"

3. at()

Gives back the element at the given index. allows for negative indexing.

const arr = [10, 20, 30, 40];
console.log(arr.at(2)); // 30
console.log(arr.at(-1)); // 40

4. Use join()

-Uses a custom separator to join array elements into a single string.

const arr = ["HTML", "CSS", "JS"];

console.log(arr.join(" - "));

 // "HTML - CSS - JS"

5. pop()

Returns the array's final element after removing it.

const arr = [1, 2, 3]; console.log(arr.pop());

 // 3 console.log(arr); // [1, 2]

6. push()

Adds one or more elements to the end of the array and returns the new length.

const arr = [1, 2, 3];
console.log(arr.pop());  // 3
console.log(arr);        // [1, 2]

7. shift()

returns the array's first element after removing it.
Its remove the first element

const arr = [10, 20, 30]; console.log(arr.shift()); // 10 console.log(arr); // [20, 30]

8. unshift()

Returns the new length after adding elements to the array's beginning.

const arr = [20, 30]; console.log(arr); 
arr.unshift(10); // [10, 20, 30]

9. delete()

removes an element from a given index, while leaving it undefined.
Note: Be careful when using. The array length remains unchanged.

const arr = [1, 2, 3]; 
delete arr[1]; 
console.log(arr); // [1, undefined, 3]

✦ Final Note

Now that we’ve explored some of the basic array methods, we’ve built a solid foundation. But this is just the beginning — there are still more powerful methods waiting to be uncovered.

In Part 2, we’ll dive into more powerful methods like splice(), toSpliced(), flat(), and more — with real examples and clear explanations.
So stay tuned, and let’s continue this learning journey together!

Ever Wonder , How Hoisting Works..?

Crosston J — Thu, 17 Jul 2025 02:58:09 +0000

Opening Lines:

Today, let's talk about Hoisting and Non-Hoisting, which are two of the most confusing but important things in JavaScript. If you know how variables and functions work before you declare them, you won't run into any tricky bugs and your JS skills will get better.

What is Hoisting?

Hoisting is JavaScript’s default behavior of moving variable and function declarations to the top of their scope before code execution.

What Gets Hoisted ?

-/ Function Declarations = Fully hoisted
-/ Variable declared with var = its hoisted but its return undefined
-/ Variable declared Let & Const = Hoisted but not initialized , they remain into TDZ . until they're defined

Lets View some example:

1. Function Hoisting

display();

function display() {
    console.log("Hello, Alice!");
}

Output:
  Hello, Alice!

Here the function is hoisted , the function call is in top . In js its execute line by line when its reach the "display()". Then its check the entire code . where is the " display()". This how its works.

2. Variable Hoisting with var

console.log(a); 
var a = 10;

Output: undefined

Because var a is hoisted, but its value (10) isn't assigned until later. Therefore "a" always returns undefined . Note this question maybe its your future interview question.

3. Variable Hoisting with let & const

console.log(b); 
let b = 20;

Error: ReferenceError: Cannot access 'b' before initialization

Why? Because let and const are hoisted but not initialized. They live in the Temporal Dead Zone (TDZ) until declared.

What is Non-Hoisting ?

Its refer to anything thing can't be used before it's declared.

eg:

When used early, let and const variables act like they aren't hoisted because they throw an error.

Function expressions and arrow functions that are assigned to variables do not hoist like regular functions do.

Example:

add(2, 3); 
const add = (x, y) => x + y;

Error: Cannot access 'add' before initialization

💡 Pro Tips From ChatGPT :

-/ Always declare your variables and functions at the top of their scope to avoid confusion.
-/ Prefer let and const for block-scoping and safer code.
-/ Understand TDZ when using let and const.

*Conclusion: *

Hoisting can make JavaScript seem random, but once you learn how it works, you'll be able to write code that is cleaner and more reliable. Always make it clear what your variables and functions are and how to use them. Don't rely on hoisting to "save" you.

“My Hour-by-Hour Experience at Code on JVM – Chennai Meetup”

Crosston J — Sat, 12 Jul 2025 16:28:48 +0000

Intro :

This is my very first Code on JVM meetup here in Chennai. I’ve attended a few meetups and hackathons before, but this one feels truly special to me. Why? Because it aligns perfectly with the future I dream of — working in the Java ecosystem, the domain I’m most passionate about. This entire meetup is centered around the Java Virtual Machine, and being here makes me feel completely at home. I’m genuinely happy and excited — words can’t fully express what this
experience means to me.

Hourly Entries :

[Time: 9:30 AM]

I just entered the campus, and wow — the structure of the building is impressive. Especially the area where the program is about to take place… the vibe there is just speechless. I really love the environment here

Most people sat in the rows of chairs arranged for the audience. But my eyes noticed something different — a corner in the room that looked like a little home setup. Even though there were plenty of chairs, I chose to sit there instead. I don’t know why I always do things like this — choosing something different from everyone else. Maybe I’m a little crazy, or even an alien in the middle of all these people. But that’s just who I am — and I kind of like it.

[Time: 9:50 AM]

The session started with Mr. Jenffer, and the topic was multithreading. I actually knew the speaker from before, so I was happy and excited to listen to him. I’ve been learning about multithreading myself lately, so today felt like the perfect chance to understand it even better.

The way he spoke and explained things was just excellent — his examples made everything easy to follow. He started by talking about concurrency, then moved on to multithreading in more detail. I even picked up some new things, like a terminal command in
VS Code: cd --/file_name, which I think is used to run code from the terminal.

What really impressed me was the way he connected his explanation to a Tamil movie, Dasavatharam. Since I’ve seen that movie and know how Kamal Haasan plays so many different roles, it was amazing to see how Mr. Jenffer used that idea to explain multithreading. It really helped me understand the concept better.

Honestly, it was such a great session — I’m glad I got to attend it. Loved every bit of it!

[Time: 11:10 AM]

After the first session came the tea break. They served both tea and coffee, and I stepped outside to enjoy the atmosphere.

While walking around, I noticed a few people looking at me — maybe because of how I looked: ID card clipped to my pants, headset on, and wearing my usual loose, different outfit. Like I said before, I always choose my own way.

After the break, they organized some games with teams of five. I didn’t have a team, but I still enjoyed watching and having fun in my own way.

[Time: 12:35 PM]

Next up was Mr. Karthick, who spoke about garbage collection. He did a good job, even though he struggled a bit to deliver the message clearly. Still, he completed his session well, and I respect that.

Watching him made me feel like… maybe next time, I should be the one to take a seminar.

It sparked a little dream in me — to stand there and share my knowledge someday.

[Time: 1:00 PM]

After lunch, they kicked off a fun and creative game. The idea was to create our own avatar for our profile, and then answer quiz questions with multiple choices. Each correct answer earned points, and the scores kept updating live.

What made me happiest was seeing my silly little avatar, along with my name, displayed on the big screen. I don’t know why, but that small moment of seeing myself up there made me feel really excited and proud.

As the game went on, players who scored high continuously had their profiles shown on the screen. I tried my best to reach the top, but I couldn’t — I knew some answers, but not all. Still, I felt good about participating.

Honestly, it was basically a quiz game, but the way the team organized it, with avatars and live updates, was such a brilliant idea. Hats off to them for making it so engaging. By then, the game moved into its final part .

Look its my crazy profile .... & it an Kahoot game

[Time: 1:20 PM]

After the game, it was time for the prize distribution — they cheered for the winners and handed out goodies, which was nice to see. Then, everyone gathered for a big group photo. Standing there with everyone, smiling for the camera, I felt proud to have been part of such a fun and meaningful day. It was a good way to end the event.

End Of My Words About The Event :

Overall, I felt completely happy to be part of this event. I learned new things, and the environment itself made me feel so good. After the sessions, I even went and spoke to the organizing team to appreciate their work. I told them, “You did a great job, and I’d love to take a seminar at one of your future events if possible.”

They said they already have many speakers lined up but promised to keep me in mind — and that gave me hope. I left the place after spending my half-day there filled with joy and love. And I know, deep inside, that one day I’ll stand on that stage and take a seminar myself.

                   ----  THE END ----

Sharpen Your Skills, Strengthen Your Mind

Lets Fall Into Some JavaScript Question:

Topic 1: Data Types

Q1. What are the primitive data types available in JavaScript?

Answer :Number, String ,Boolean, Null, Undefined, Symbol, BigInt

Q2. What is the difference between null and undefined?

Answer:

null → intentional absence of a value.

undefined → variable declared but no value assigned.

Q3. Is JavaScript a statically typed or dynamically typed language? Why?

Answer:
Dynamically typed → variable types are determined at runtime, not declared explicitly.

Topic 2: Operations

Q1. What are the different types of operators in JavaScript?

Answer:
Arithmetic, Comparison, Logical, Assignment,Bitwise, Ternary (conditional), typeof, instanceof.

Q2. Explain the difference between == and ===.

Answer:

==  → checks value after type coercion.

=== → checks value and type (strict equality).

Topic : Logical

Q1. What are the logical operators in JavaScript?

Answer:

=> && (AND)

=> || (OR)

=> ! (NOT)

Q2. What will this return?

console.log(true && false || !false);

Answer:

true && false → false

!false → true

false || true → true

Q3. What is the output of:

console.log(0 == false);
console.log(0 === false);

Answer:

0 == false → true (type coercion)

0 === false → false (different types)

Why?

It all comes down to the difference between:

== → loose equality

=== → strict equality

Now you have the dout , Why number turn into boolean .

Because in the ECMAScript spec:

When you compare Number and Boolean with ==,
JavaScript always converts the boolean to a number.

false → 0

true → 1

Then compares number with number.

That's all for today , It may help you to improve your knowledge .

Time For JAVA SCRIPT....

Crosston J — Mon, 07 Jul 2025 14:50:31 +0000

What is java Script :

JavaScript is a scripting language used to make websites interactive.
It's also a dynamically typed language, meaning you don’t need to explicitly declare data types.

Example :

let x = 5;
x = "Hello";

Basic Features of JavaScript:

Variables
Functions
Events
Loops
Conditions

What is DOM Manipulation :

DOM Manipulation means using JavaScript to change the content, structure, or style of a web page after it’s loaded.
letting you update text, add elements, remove elements, change styles, and respond to user actions dynamically.

Simple Words:

Imagine your web page is like a notice board at school.

The board itself is the** HTML structure (DOM tree) **— with pins and papers already set up when the page loads.

Now, you (JavaScript) walk up to the board and:

Change the text on a pinned note
Add a new announcement to the board
Remove an outdated paper
Highlight something in red to grab attention

That’s exactly what DOM manipulation does — it lets your JavaScript “walk up” to the webpage, find the right element, and change it on the fly without replacing the whole board.

Code:

let name = "Alice";
let age = 21;

console.log("My name is " + name);
console.log("I am " + age + " years old.");

Output:

My name is Alice
I am 21 years old.

Other things lets talk tomorrow blog......

The Hidden Hero of Web Development: Backend

Crosston J — Thu, 03 Jul 2025 02:34:30 +0000

A Intro :
So in upcoming days , lets shower into backend side .we move
bit by bit ,now jump into backend topic.

what is backend :
The another name of backend is called as server side ,what are all the user can see that's all frontend and what the user don't see . that's know as backend . so now you have some idea ,what is backend.

It handles all the data, logic, authentication, database operations, and server communication behind the scenes.

Some Example Image:

Its for just kidding . but its shows the exact example - what the user can see that's frontend, what the user don't see , that's know as backend.

Why backend is important and why its use :

So without backend ,we can able to run the website properly. The backend is used to manage and control everything that happens behind the scenes of a website or application. It takes care of storing and retrieving data, handling user authentication (like login and signup).

Technologies Used in Backend Development :

Backend development uses a variety of technologies to build powerful, secure, and scalable web applications.

The core of backend starts with programming languages like Java, Python, PHP, Ruby, and JavaScript (Node.js). Each with its own strengths.

To speed up development and manage complex systems, developers often use frameworks such as Spring Boot for Java, Django for Python, or Express.js for Node.js

And another backbone of Backend is databases to store and manage data . the most common ones include MySQL, PostgreSQL, and MongoDB.

Along with these, developers use tools like Postman for API testing, Git for version control for running applications in containers.

All these technologies come together to ensure the backend works.

Conclusion :

So Today you know little bit of what is backend & why its use and what technology where used , so lets break it deeply Day by day .

“One Step Closer to My Dream -The Day of Build 2 Learn”

Crosston J — Tue, 24 Jun 2025 18:03:52 +0000

Its not about the tech content , just myself and what I feel after I went to the meetup .
21/06/2025 I cant forget those moments . The day I walked into the start of my dream. Just one step at a time... and then I lifted my eyebrows, raised my head, and looked up at that tall building covered in glass. In that moment,

My heart whispered:
“Yeah… you just made the first real step toward your dream”.
I’ve taken many steps before this. But this one?
It was different.It was unexplainable. Then I move forward and saw the maintenance & structure of those build , Its really unexplainable one .

Finally I entered to the building .honestly, words can’t describe how happy I felt .With all the happiness I enter to the working spot . Actually It was my first time ,what I'm exploring .

Then they start the session and set some team and do some project . myself and my team got a marriage website topic , In case that we have to solve the problem .what still goes on . therefore we find some problem .but Its take too long time ,so we don't have enough of time to build an website and execute .however we try our best and build the website with those problem solving .

The another twist is , suddenly they said like all the team have to present their project in front of all . my team members are get nervous about the presentation , even i also feels the same .but i act like , yeah that's completely fine for me .Then our turn comes. before i went there.

I told myself:
“You’re the only one who can do this. You’ve got this. Just smile and go.” And with that damn confident smile, I started presented . And i fulfill with it .after my end of presentation everyone clapped and cheer for me & my team . Afterward, some even told me, “Your presentation was perfect.”

That moment? I’ll carry it forever.

Finally its move to end of the session .then we took some group photo. moreover i completely enjoy each and everything .the confident i have , what i feel after all .each & everything its make the moment unforgettable .this what i feel in " build 2 learn meetup"

Its time to gratitude :

Every bit of credit goes to the Almighty.
Then, a huge thanks to the Payilagam Institution, for helping me achieve the first step toward my dream.

Special thanks to Mr. Muthu, Mr. Vijay, and the other trainers for making it possible.
A heartfelt thank you to the Build 2 Learn team for organizing this special event.
And to my fellow academy mates and session mates — thank you for making me feel happy and peaceful.

“The Art of Version Control: Understanding GIT”

Crosston J — Thu, 19 Jun 2025 03:08:10 +0000

What is Git?

-> Git is a version control system that helps developers track changes in their code.
-> It allows you to save different versions, collaborate with others, and go back in time if something breaks.

Example :

Git is like a time machine for your code.
You can see what changed, who changed it, and undo mistakes anytime.

Why Git is Used:

1.Track Code Changes
Git saves every version of your code so you can go back anytime.

2.Work with a Team
Multiple developers can work on the same project without messing up each other’s code.

3.Undo Mistakes
If something breaks, you can easily roll back to a previous version.

"So Now you have The Idea About Git & Why Its Used "

Step-by-Step: Install Git on Linux Mint:

" After This your Git is Installed in your PC"

Next Steps (Optional but Recommended):

After Git is installed, you usually want to configure your identity (so Git knows who’s making the commits):

So if you not config, still Git works But when its ready to "commit" in that time you have to config. your username & email

-> Actually is the next process . if you try to push the code in git lab / git hub . if you're ready to push then you have to config.

Conclusion :

Git is a powerful version control tool that helps developers track changes, collaborate, and manage their code safely. We covered what Git is, how it works, and how to install and configure it on Linux Mint.

Up Next :
Tomorrow, we’ll learn how to push your code to GitLab step-by-step!

“Do You Know Why Some Websites Shine Brighter Than Others? It’s " SEO”

Crosston J — Mon, 16 Jun 2025 15:13:30 +0000

What is SEO?

SEO (Search Engine Optimization) is the process of improving a website or web page so that it ranks higher on search engines like Google, Bing, or Yahoo — helping more people find it organically (without paid ads).

Simple Words To Understand :

SEO helps your content appear at the top when someone searches for related topics online.
So now you have some idea about what is Search engine Optimization.

How Does SEO Work?
Eg:

Imagine the internet as a huge library and Google as the librarian.
Now when someone asks:

“What is LGBTQ ?”
Then Google (the librarian) looks through millions of pages to find the most relevant, helpful, and trusted one — and shows that on Page 1.

SEO is the method that helps your page be one of those top results.

SEO Works in 3 Main Steps:

1. Crawling :

They collect content from every website to understand what it's about

2. Indexing :

It organizes it based on topics, keywords, relevance, and structure

3. Ranking :

When a user searches, Google finds the most relevant results from its index and ranks them

Ranking depends on many signals like:

     -> Keywords used

     -> Page quality and structure

     -> Website speed

     -> Mobile-friendliness

    -> Backlinks (other sites linking to yours)

My Opinion :

After hearing this i may interested on it . moreover what i give here is just a beginning line . you can search more about it like ,** What are the types of SEO, What’s the difference between SEO and paid ads (SEM)?, What happens if a website has no SEO? ,What is the main goal of SEO? . so there are multiple questions About SEO **, so find it and improve your Skills...

Conclusion :

SEO helps your content get found on search engines like Google. By using the right keywords, writing clearly, and improving your page, you can reach more people. It’s a smart skill for anyone who creates online content. Start small, keep learning, and grow step by step.

Linux Is Not Just A Tree , Its An Forest...

Crosston J — Sat, 14 Jun 2025 03:39:34 +0000

Intro :
When I heard about this word linux , I have an idea like it's An Operating System . If I Said In Different Words Mean -Its an single OS like Windows or MacOS.but Actually When i Started to Learn .I feel Its not A single Tree, Its an forest. So Lets Talk About The Linux.

What Is LINUX ?
Actually Linux is an open source And it's Build-on but peoples. Moreover linux is not just a single OS , Its have the different Types Of Flavors & and each use for different usage .

List Out The Flavors:

-> Ubuntu
-> Linux Mint
-> Fedora
-> Debian
-> Arch
-> Kali Linux
-> Parrot OS
And ETC...

These Are The Types & Its usage.

So in short:

Windows = 1 flavor by Microsoft
Linux = many flavors from many creators, all using the same engine

Do You know , Why So Many Versions In Linux ?

Buz It's An Open-source , anyone can Use The Kernal & Build Their our versions , So Different Team Builds Different Types Of Version / Flavors . Based On Various Goals .

" OverView Of Linux & Its Flavors: "

" Disadvantages of Linux..."

We Need to see the advantage of an OS & The same the disadvantage too,So Lets see the Disadvantage of linux

-> Some Popular Apps Don't Work

You can't use full versions of software like Photoshop, MS Office, or Premiere Pro directly. You’ll need alternatives or tricks like Wine.

-> Not the Best for Gaming

Many popular games don’t support Linux well. Online multiplayer games may not work due to anti-cheat software issues.

-> Hard to Learn at First

If you're new, using the terminal and installing things without a simple installer might feel confusing.

Conclusion :

So finally, what I understood is —

Linux is not just an operating system... it's a whole universe.
It gives the freedom to choose, to break, to build, and to learn.
Everyone sees Windows as a product.

But Linux? It's a community, a craft, and a culture.
And this post — it’s just my beginning.

I’m not an expert. I’m just someone who stepped into the forest and decided to walk...!

Windows OS: The Digital Gateway to Your PC & Some Secret of Windows

Crosston J — Fri, 13 Jun 2025 04:13:50 +0000

Introduction :

In the digital world we live in today, an operating system is not just software—it’s the heartbeat of your computer.

What is Windows?

Windows is an Operating System (OS) developed by Microsoft.

What's an Operating System (OS)?

An OS is like the manager of your computer.
It controls all the hardware (keyboard, mouse, memory, storage, screen, etc.)
And lets you interact with the computer using apps, files, games, and settings.

** Example to Understand:**

Imagine your computer is like a restaurant:

Hardware = Tables, chairs, stove, food

Operating System (Windows) = The manager who controls everything

Apps (like Chrome, MS Word) = The chefs or workers who do the tasks you ask for

Without the OS, your computer is just a bunch of hardware with no control or interface.

Why windows ? why do most people use it.

Its user friendly Interface
Best for Gaming
Use in Office & Schools
Developing user-friendly

Windows 10 vs Windows 11 – What’s the Real Difference?

Windows 11 is a sleek, modern upgrade over Windows 10. It brings a centered Start menu, rounded corners, and smoother animations that make it feel more polished.

While Windows 10 focuses on stability and wide compatibility,

Windows 11 is built for the future—with better multitasking tools like Snap Layouts, improved gaming performance, and optimized speed for newer hardware.

If you love the classic feel, Windows 10 still works great. But

If you're ready for a fresh, faster experience, Windows 11 is worth the jump.

What is 64-bit in Windows?

When we say Windows is 64-bit, we’re talking about how the computer’s processor (CPU) handles data and memory.

It’s a type of architecture — like a blueprint — for how the system works inside.

*In One Line With Simple words *

64-bit Windows means the OS and processor can handle larger memory, more data, and run faster — making it the standard for modern computing.

Secrets of Windows OS You Probably Didn’t Know

1.You’re Already Paying for Windows — Even If You Didn't Know It

Most laptops and branded PCs come with Windows pre-installed, but you’re actually paying for it in the device’s price.

Manufacturers include the cost of a Windows license (₹5,000–₹15,000 or more) silently.

You don’t get a choice — even if you wanted to use Linux or something else.

2. Pre-installed Software = Hidden Bloatware

Windows often comes with extra software you didn’t ask for — like antivirus trials, Xbox apps, or games.

These are called bloatware, and many companies pay Microsoft to
pre-install them.
