What is JavaScript?

JavaScript is one of the most widely used programming languages because it is a building-block of the interactive web that we know today. It is used for developing interactive websites, web servers, mobile applications, games, and more.

With JavaScript, the possibilities are endless.

What makes JavaScript so powerful is its ability to manipulate the DOM (Document Object Model), the structure of web pages. With JavaScript, you can add, modify, and remove the elements of a web page and create the interactive behavior that makes the web so powerful today.

Without JavaScript, the web would just be a set of static web pages, showing the same content all the time. If you cannot imagine a world without the interactive web, you cannot image a world without JavaScript.

JavaScript was originally intended to be used for the web. It was designed to run in the browser, so by default, browsers can understand and interpret JavaScript code.

With modern tools like Node.js, now we can also run our code in the terminal. This is very powerful and used very frequently by developers.

Career Opportunities

If you learn JavaScript, you will find career opportunities in almost every field of your choice. JavaScript skills are in high demand and widely sought by employers.

These are just some of the most popular ones. Each one has its own unique applications, but they are so diverse that I’m sure that you can find a JavaScript library that fits your needs.
