In this JavaScript tutorial, we are going to learn JavaScript for beginners and professional both.

A programming language that adds interactivity to your website is JavaScript. This happens in games, when buttons are pressed or with data entry on forms, in the behavior of responses; with dynamic styling; with animation, etc. This article helps you get started with JavaScript and encourages your understanding of what is possible.

What can in-browser JavaScript do?

Modern JavaScript is a programming language that is "safe." It does not provide memory or CPU with low-level access, because it was originally created for browsers that do not require it.

The capabilities of JavaScript greatly depend on the environment in which it keeps running. For example, Node.js supports functions that allow arbitrary files to be read/written by JavaScript, perform network requests, etc.

In-browser JavaScript can do everything related to manipulation of the web page, user interaction, and the webserver.

for example, In-browser JavaScript allows:

• Change existing content, modify styles, add new HTML to the page.

• React to user actions, run on mouse clicks, move pointers, press keys.

• Send requests over the network, download, and upload files (so-called AJAX and COMET technologies) to remote servers.

• Get cookies and set them, ask a visitor questions, show messages.

• "Please remember the client-side data" (local storage).

Features of JavaScript:

• It is a language for scripting and has nothing to do with Java. It was originally called Mocha, then changed to LiveScript, and finally to JavaScript.

• JavaScript is a programming language based on an object that also supports polymorphism, encapsulation, and inheritance.

• In addition to the browser, you can run JavaScript on the server and on any device that has a JavaScript engine.

I hope this JavaScript tutorial will provide you full basic knowledge of JavaScript.
