What is JavaScript?

The Javascript web language

JavaScript is a programming language that allows you to define elements on a web page or on a web server. It is one of the three basic programming languages of the web (with HTML and CSS).

As soon as you visit a web page, a JavaScript code is automatically executed. Your web browser executes the JavaScript code instructions before returning the results to you.

It can be used to create interactive websites, games, and many other things. For example, you can create forms or cookies, validate entries, etc. In short, Javascript allows you to create dynamic web pages.

This programming language is rather easy to learn, even for beginners in programming. However, it can take some time to learn all the concepts necessary to fully exploit Javascript.
