JavaScript is a lightweight, object-oriented programming language used on the client and server-side allowing you to make interactive web pages. It enables dynamic interactivity on websites when applied to an HTML document.
This full-fledged, interpreted programming language helps users to build modern web apps to interact without reloading the page every time directly. It is generally used to modify HTML and CSS dynamically to update a user interface via the Document Object Model (DOM) API.
JavaScript is so popular that it has become the most used programming language in the world. Its popularity is because it’s versatile enough for various applications, like hardware controls, software, and servers.
