Robert Lynch — Thu, 22 Dec 2022 18:56:34 +0000

There are many commonly used JavaScript methods, as the language has a large and comprehensive standard library. Some of the most commonly used methods include:

console.log()

This method is used to log messages to the console. It is often used for debugging and testing purposes.

document.getElementById()

This method is used to retrieve an element from the DOM (Document Object Model) by its unique ID.

array.forEach()

This method is used to iterate over the elements of an array and perform a specific action on each element.

string.split()

This method is used to split a string into an array of substrings based on a specified delimiter.

string.replace()

This method is used to replace a specified value in a string with another value.

Math.random()

This method is used to generate a random number between 0 (inclusive) and 1 (exclusive).

array.sort()

This method is used to sort the elements of an array in place, according to their natural sort order or a custom sort function.

array.map()

This method is used to create a new array by performing a specific action on each element of the original array.

object.hasOwnProperty()

This method is used to check if an object has a specific property defined directly on it (as opposed to inherited from its prototype).

string.trim()

This method is used to remove leading and trailing white space from a string.

These are just a few examples, but there are many other commonly used methods in the JavaScript language.

Learning to code for beginners

Learning to code can be a rewarding and challenging experience. With the right resources and mindset, anyone can learn how to program and create their own software, websites, and applications.

If you are new to coding, the first step is to choose a programming language to learn. There are many popular languages to choose from, each with their own strengths and uses. Some popular options for beginners include Python, JavaScript, and Java.

Once you have chosen a language, it's time to start learning the basics. There are many online resources, tutorials, and courses that can help you get started. Some popular options include Codecademy, Khan Academy, and Coursera.

In addition to online resources, there are also many books and guides that can help you learn to code. These can be a great way to supplement your online learning and help you understand the concepts in more depth. Some popular books for beginners include "Learn Python the Hard Way" and "JavaScript for Beginners".

As you learn the basics of your chosen language, it's important to practice and apply what you have learned. This can help you develop your skills and build your confidence. One way to do this is by completing coding challenges and exercises on sites like HackerRank and Code Wars.

Another way to practice and learn is by working on small projects. This can be anything from a simple program that prints "Hello, World!" to a more complex application or website. As you work on your projects, you will learn new concepts and techniques, and you can also share your work with others to get feedback and help.

Learning to code can be a rewarding and challenging journey. With the right resources and mindset, you can learn the skills you need to create your own software and applications. Whether you want to build your own website, create a new app, or just learn more about how computers work, learning to code can open up new opportunities and possibilities.

Type Conversion.

Type Conversion

Implicit: byte b = 1; //takes 1 byte of memory
int i = b; //integer takes 4 bytes
(you can copy a byte into an int, but not
an int into a byte). // won't Compile
Explicit: float f = 1.0f;
int i = (int)f;(casting)
Conversion between non-compatible types:
string s = "1";
int i = Convert.ToInt32(s)
int j = int.Parse(s);

Convert Methods():Examples

         ToByte() //To convert to a byte
         ToInt16() //To convert to a 16 "Short"
         ToInt32() //To convert to a 32 "int"
         ToInt64() //To convert to a 65 "Long"

High demand for devs, Grueling hiring process.

Given the latest data on the demand for software Developers, I'm curious why companies don't fast track the interview/hiring process.
Or even offer on the job training for entry level/junior Developers who show potential
