What new features are introduced in React- version 17?

Alicia Johnson — Fri, 28 Aug 2020 12:53:07 +0000

React Fiber(React v16) is amazing and has taken several big steps to enhance the performance of the developer as well as the quality of the applications developed with React. It has introduced several changes in the new version and some of them are as below:

New Lifecycle Methods- The new lifecycle methods are switched with the deprecated lifecycle methods. These two methods are: getDerivedStateFromProps and getSnapShotBeforeUpdate.
Native Component Stacks- In React 17, component stacks are created using a different process to thread them together from regular native JavaScript stacks. This helps you to locate the completely symbolical React component stack traces in the production process.
Removing Private Exports- In React 17, private exports have been eliminated. React Native for Web was the only project that used them, and they have already completed a migration to a new approach that does not rely on private exports.
Optimizing Effect cleanup- In the past, the cleanup feature would run synchronously before the next frame was created. In fact, most apps do not allow screen updates to be delayed while cleanup methods are operating. And now they're going to run asynchronously after React has made the next frame. This is supposed to result in faster switching times between components. You can also use the useLayoutEffect framework to run a cleanup process that blocks the rendering loop.
No More Event Pooling- Event pooling is extremely messed up and does not have any functionality for major browsers. Instead, it might result in some odd bugs when operating with multiple components that experience the same case. One event handler might set an event to be null, so the other components using an event might run into a null variable error. To sum up, the newer version of React will enable users to access event fields anytime you need them.

Conclusion

These are just some of the changes that I noticed. React version 17 has come up with more such changes that will prove to be very efficient in the long run.

Why do I think Dot NET is Better Than Java?

Alicia Johnson — Fri, 21 Aug 2020 13:51:27 +0000

There are a lot of resemblances among Dot Net and Java, but there are some significant differences that make me want to discuss where and when Dot Net is the best choice for your desktop, web, and mobile software development project. When we talk about Java, it is a programming language while Dot Net is a framework supported by Microsoft.

.NET and Java both seek to enhance application creation through the availability of a range of defined modular components and services. Developers can focus on business requirements instead of programming basic services with standard components and services at their disposal.

Java and .NET have been built to allow programmers to build Web applications that are "steady." A 3-stage framework consists of a client level, server level, and database level. Dot NET and Java both provide transactions that allow business processes and data in databases to be triggered.

Why Dot NET is better than Java?

It is the most secure- In Dot Net, safety issues have been properly handled and the new innovations have been applied. For open-source projects such as Java, lack of infrastructure, and qualified assistance is hardly feasible. Consequently, Java Runtime's regular updates and other elements ruin user interactions and cause distractions to others.

It supports cross-platform web development- Dot NET promotes the development of cross-platform applications that allow the user to create Windows, Linux, and Mac applications. The whole backend will use the same C# code in much clearer terms.

It provides better performance- The huge achievement that Dot NET has acquired is its brilliant performance. All the new updates and improvements lead to an optimized code that in return boosts the performance. The most important thing is that you don't have to change the code in reality.

It has a mature runtime as CLR- In many technical details, the Common Language Runtime (CLR) is superior to JRE or JVM. It is because JVM is a compiler and simply translates Java Byte code into an extensive instruction for, and not directly for the computer. This is also still sluggish and needs daily updates to accommodate further operating systems. In comparison, the CLR of Dot Net is not the case.

Bottom Line

If you trust in Microsoft's strengths and its ASP.NET framework, it's time to join in, rather than wander around dangerous open-source environment, where you have to go extra miles to achieve something significant. Of course, a team of seasoned Dot Net developers is needed to make the most out of it and give remarkable results.

What is software tool and why it can be found in the chrome folder?

Alicia Johnson — Thu, 23 Jul 2020 07:14:00 +0000

If you noticed a hidden process or program running in Task Manager with the name "Software Reporter Tool.exe" which causes high utilization of the CPU/disk and you think what it does in your machine, then you've come to the right place.

Software Reporter Tool is a discrete function in Google Chrome that tracks your Chrome installation and informs whether any add-ons interfere with the browser's normal activity. The method is not related to the internet but is used exclusively by the user to identify programs that may interfere with it.

Though the tool is useful, it can trigger problems on your machine at times. Software Reporting Tool often consumes loads of memory and creates issues with high CPU use and disk use. It can bog down the computer and can cause other applications to crash. Even many users worried about privacy may not want to allow this tool to run on their device because it will send the report of the scan results to Google.

Pros of a software reporter tool-

It can get harmful software and malware removed from your computer.
It can help remove ineffective extensions and add-ons from Google Chrome that were installed automatically, without your knowledge, by third-party software.

Cons of a software reporter tool-

Often it uses too much RAM and creates high uses of the CPU and problems of disk use. Your machine can slow down.
Often it can identify and uninstall certain Google Chrome apps and extensions or add-ons which it considers dangerous but the apps and extensions are actually safe and helpful and have been installed deliberately by you.

Can you disable it?

So far, we have understood what is software reporter tool and why its there in the chrome folder?

It's time to learn if we can disable or remove the software reporter tool. To answer it, yes, we can remove it.

Disable Software Reporter Tool Using Registry Editor

We must take advantage of the DisallowRun key to prevent the Application Reporter Tool from running.

To open the RUN dialog box, press the "WIN+R" key combination, then select regedit, and press Enter. The Registry Editor will be accessed.
Now go to the main below:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies
Create a new key under the Policy key and set its name to Explorer.
Create a new key under Explorer, and set the name to DisallowRun
So the final key path is:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun
Now select DisallowRun key and right-click on the "New-> String Value" option in the right-hand pane. Set the new name of string as 1
Double-click on 1 string and set Software Reporter Tool.exe as its value
Disallow_Software_Reporter_Tool_Registry_Editor.png

This is it. You may need to reboot your machine to take effect. Computer reporter tool will now be blocked from running in context.

5 Best Android Emulators For Windows PC

Alicia Johnson — Tue, 14 Jul 2020 12:31:37 +0000

When you are thinking about running Android on your Windows PC, then let me tell you that there's no scarcity of emulators in the market. There are several explanations for those who are curious about what is the need to have an Android emulator on your Windows PC. Some of the reasons include android app developers can test their apps right on the desktop, gamers can play Android-specific games on a bigger display, and the list is endless. So, it may be enticing to try one now that you see the various advantages of using Android emulators.

Find the list below that I have curated including the best android emulator for PC :

Bluestack- BlueStacks is among the best Android emulators you'll find on Windows, without any doubt. If you want to have an experience of Android devices on Windows PC then BlueStacks is a fantastic emulator at your fingertips as a general user. It's has seen a lot of improvements over the ages and the latest BlueStacks are based on Android 7.1.2 which is Nougat.
Android Studio- This is one of PC's most common android emulators. It comes with pre-defined settings for different Android devices including phones, tablets, Wear OS, and Android TV. It uses features from built-in media players such as replay, audio, video, etc. This emulator offers a real Android computer with diverse features. It can imitate incoming texts and calls, identify the location, other sensors for hardware, and much more.
LDPlayer- If you're searching for a gaming-optimized Android emulator for Windows 10 then let me give you the newest emulator in the market, LDPlayer. The simulator can run smoothly on Intel Windows PCs. As for the Android version, for higher performance and integration, the LDPlayer runs on Android Nougat (7.1.2)
MEmu Play- MEmu Play is another fantastic Windows Android emulator that has been getting tons of visibility recently. Naming a specific or even a few features is a tough job given MEmu comes packed with a lot of useful functionality. Some of the emulator's most influential features are the fact that it supports both Intel and AMD CPUs which is perfect in terms of performance.
Gameloop- Gameloop is yet another way to experience Android games of the highest standard on Windows PCs. It's a dedicated gaming emulator designed for gamers wanting to play a variety of available Android games on desktop PCs. You might be shocked to learn that Gameloop – previously named Gaming Buddy-was created by Tencent as part of the gaming project on the desktop-mobile.

To Sum Up...
Android emulator for PC functions with both hardware and software on the concept of clear platform visualization. It allows us to fit a host system in translating ABI. The user then combines it with the operating system and executes it on their machines like a program or application.

Either way, it is possible to simulate Android on a PC and much simpler than before. Some old favorites have left the room or became unusable (Andy, AmiduOS, and Leapdroid), but for most people, anything else will work well.

React onClick Event Handling

Alicia Johnson — Thu, 09 Jul 2020 09:20:16 +0000

In React, events can be treated very close to the way we do in HTML, such events are like clicking, changing, mouseover, etc. But the syntax of 'react events' is written in camelCase.

In React, the onClick handler lets you call a function and perform an action when you click on an item. OnClick is the staple of every React device.

For example: "onClick" instead of "onclick" and the function that this event will point to being written in curly braces, e.g. onClick={function}.

We'll just think about treating things with 'onClick' in this blog. The onClick handler lets you call a function and perform an action when you click on an item.

Create a new project using this command:
npm create-react-app reactOnClick

here, reactOnClick is the name of the project.

Now, go to the project directory and start it-

cdreactOnClick
npm start
You should have your project started on the localhost.

React onClick event handling is pretty easier to understand and run.

Whenever after clicking a button, connect, or basically any item you need to perform an action, you can use the event handler onClick.

The onClick event handler is therefore one of the most efficient and most-used devices in the React tool belt.

How to start preparation for JavaScript interview

Alicia Johnson — Thu, 18 Jun 2020 09:12:46 +0000

What is JavaScript?

Javascript is one of the most widely used web programming languages. It is mainly used to build interactive Web applications and games on the client-side. Even Javascript can be used as a programming language on the server-side. It is a complex, loosely typed, a high-level programming language based on prototypes and multi paradigms.

What does the hiring team look for?

In an interview that involves programming skills, it is not just about the Syntax. It's about realizing how to better use the concept (and syntax) of JavaScript to rectify the final problem.
How much do you functionally understand the language? How efficiently can you use these theories to solve real problems with the work?
How do you write the code (conventions for encoding, syntax, reusability)? Do you want to spend half of your life debugging syntax errors?
What is your process of thinking? How do you think of the problem, find a solution, and turn it into a working code?

Apart from this, they look for your communication skills and how much confidence you have while you are answering them. So, constantly working on both technical skills and soft skills is important.

Now, below are some of the skills that you must cover before appearing for that dream interview:

Javascript core concepts such as hoisting, closures, scopes (lexical, function, block), this keyword, prototypal inheritance, call-bind-apply, throttle-debounce, callback, callback-hell, etc.
Javascript recent trends such as ES6 syntax, typescript, classes, arrow functions, promises, async-await
Learn one framework out of ReactJS, Angular, VueJS
Development and build process such as Visual Studio IDE, npm, babel etc.

Final Preparations for the Interview

Lastly, once you think that you have prepared yourself extensively, then try to look at some of the JavaScript Questions that have been asked in the interviews. These questions will help you a lot when you are in front of the interviewer and will make you seem confident. These are frequently asked questions and very basic ones too, so it’s always good to know their answers.

Moving ahead and depending upon the profile you are applying for, there might be a requirement of having extensive knowledge of Advanced JavaScript Questions . Preparing for one step ahead will gradually boost your confidence and make you aware of the many concepts of the language.

Have a thorough look at these questions before you step in for the interview as they will keep your memory fresh with the JavaScript concepts. Your comprehensive knowledge will reflect in the interview and will definitely help you land the job of your dreams.
