How does JavaScript Work?

by Pritam Sau - August 03, 2022

JavaScript is a client-side scripting language and one of the most efficient, commonly used scripting languages. The term .client-side scripting language means that it runs at the client-side( or on the client machine) inside the web browsers, but one important thing to remember is that client's web browser also needs to support JavaScript or it must be JavaScript enabled. Nowadays, most modern web browsers support JavaScript and have their JavaScript engines. For example, Google Chrome has its own JavaScript engine called V8.

It totally depends on the web developers how they use JavaScript and for what, because it can be used for several things in web development. One of the most common uses of JavaScript is to validate data given by the user in the form fields.
