What is JavaScript? JavaScript is a scripting language that enables web developers/designers to build more functional and interactive websites. Common uses of JavaScript include: Alert messages Popup windows Popup windows Dynamic drop down menus Form validation Displaying date/time JavaScript usually runs on the client-side(the browser's side), as opposed to server-side(on the web server).
