JavaScript is a essential scripting language that powers many features on websites. Without JavaScript, many websites will not function properly. In this guide, we will show you how to enable JavaScript in different web browsers.
What is JavaScript?
JavaScript is a programming language used to create interactive features on web pages. It can be used to create animations, validate forms, and interact with APIs, among other things. JavaScript runs on the client side, meaning it runs in your browser rather than on the server.
