It is an essential technology for web developers and is supported by all modern web browsers. It also has a high demand in the Job market as of 2024.
📄️ Development Environment
In order to write and run JavaScript code, you need to set up a development environment. A development environment is a set of tools and configurations that allow you to write, test, and debug code efficiently. In this guide, we will walk you through the process of setting up a development environment for JavaScript. Here are some of the tools you will need to set up a development environment for JavaScript:
📄️ Javascript in Browser
As said in the previous section, JavaScript was originally designed to run in web browsers so every browser has a JavaScript Engine that executes JavaScript code. In this section, we will be talking about how to run JavaScript in the browser.
📄️ First JavaScript Program
In this section, we will write our first JavaScript program. We will create a simple program that displays a message in the console. Let's get started!
📄️ Separation of concerns
Separation of concerns is a design principle that encourages developers to separate different parts of a software application into distinct sections. This helps to improve the readability, maintainability, and scalability of the codebase. In this guide, we will discuss the concept of separation of concerns and how it can be applied to web development using JavaScript.
📄️ JavaScript in Node.js
In this section, we will only talk about how to check if Node is installed on your computer and how to run JavaScript code in Node.js.
📄️ How JavaScript Works
In this section, we will be talking about how JavaScript works. We will be talking about the JavaScript Engine, the Call Stack, and the Event Loop. Let's get started!
