JavaScript Basics

JavaScript is the programming language you should use to add interactive features to your website (for example, games, events that occur when buttons are pressed or data is entered in forms, dynamic styling effects, animation, and much more). plus). This article will help you get started with this extraordinary language and give you an idea of ​​what it is possible to do with it.

What is JavaScript really?

JavaScript is a robust programming language that can be applied to an HTML document and used to create dynamic interactivity on websites. It was invented by Brendan Eich, co-founder of the Mozilla project, the Mozilla Foundation, and the Mozilla Corporation.

You can do almost anything with JavaScript. You can start with little things like carousels, image galleries, fluctuating layouts, and responses to button presses. With more experience, you'll be able to create games, 2D animations and 3D graphics, embedded database-driven applications, and much more!

JavaScript itself is quite compact yet very flexible, and developers have written a lot of tools on top of the core JavaScript language, unlocking a lot of additional functionality with minimal effort. This includes:

Browser Application Programming Interfaces (APIs) — APIs built into browsers that offer functionality such as dynamically creating HTML content and setting CSS styles, to capturing and manipulating a video from the user's webcam, or generating 3D graphics and video displays. sound.

Third-party APIs, which allow developers to incorporate features into their sites from other content providers such as Twitter or Facebook.

Third-party frameworks and libraries that you can apply to your HTML so you can quickly build and publish sites and applications.

Since this article is only supposed to be a light introduction to JavaScript, the intention is not to confuse you at this stage by talking in detail about what the difference is between the core JavaScript language and the different tools listed above. You can learn all of that in detail later, in the Learning Area on MDN, and on the rest of MDN.

Below are some aspects of the core language and you'll also play with a few features of the browser API. Have fun!
