JavaScript, to put it simply, is a programming language used to create interactive websites. If you consider the basic components of a website, HTML describes and defines the basic content and structure of the website, and CSS instructs the browser how to display this HTML content by specifying elements like colour and font.
You can create a website with only HTML and CSS, but it won't accomplish anything lot. JavaScript adds functionality, which gives the webpage life. It is in charge of user-interactive elements like drop-down menus, modal windows, and contact forms. Additionally, it is used to make interactive maps, video players, and animations.

Why learn JavaScript?
JavaScript experts are versatile
Languages don't come more flexible than JavaScript. Once you've learned it, the options are virtually limitless: you can use Angular for client-side (frontend) coding and Node.js for server-side (backend) coding. Utilizing React.js, React Native, and Electron, you can create web, mobile, and desktop applications and even get into machine learning.
JavaScript is beginner-friendly
JavaScript provides one of the more approachable entrance points into the world of coding when compared to many other programming languages. The best part about it is that every current web browser already has it installed, so you don't even need to set up a development environment to get started using JavaScript!

Another benefit of choosing JavaScript as your first programming language is that you get immediate feedback and can see results from your work with very little code. Additionally, there is a sizable JS community on websites like Stack Overflow, so you'll have no trouble finding help as you learn.
Should you learn vanilla JavaScript first?
It can be tempting to skip ahead to those time-saving frameworks and libraries we just discussed when learning the language—and many developers do. There are, however, a lot of strong justifications for learning plain JavaScript first.
While JavaScript frameworks might make your job easier, you can only go so far if you don't comprehend the underlying ideas of these frameworks. Abhishek Nagekar, a front-end developer, explains how his failure to learn vanilla JavaScript caught up with him once he began learning the JavaScript frameworks Node and Express:

What is the best way to start learning JavaScript?
Therefore, learning this language is a must if you want to work as any type of web developer, and you should start with JavaScript in its most basic form. Senior developer Marven demonstrates how long it should take to learn JavaScript so you can estimate how long to allow for language acculturation.
Getting your hands dirty is the greatest approach to begin learning JavaScript. After reading about the language and how it functions, try using it in your browser. Simply click "View" and choose "Developer" from the drop-down menu if you're using Google Chrome. You can then choose "JavaScript Console" and get started.
