JavaScript JavaScript is a client-side scripting language, which means the source code is processed by the client's web browser rather than on the web server.This means JavaScript functions can run after a webpage has loaded without communicating with the server.or example, a JavaScript function may check a web form before it is submitted to make sure all the required fields have been filled out. The JavaScript code can produce an error message before any information is actually transmitted to the server.
