JavaScript is a Scripting language and it is an interpreted language. So we do not need to compile the JavaScript code. It is often called JS. It was developed to make websites more interactive and user-friendly. With the help of javascript, we can do many things on the browser window like: change any text, change any font color, or send requests to the server without reloading the web page. In javascript, we simply create functions and call them. JavaScript is similar to other programming languages but also javascript provides some additional features that other languages do not provide.
