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). One benefit of doing this is performance. On the client side, JavaScript is loaded into the browser and can run as soon as it is called.
