/*
JavaScript can be used to do neat things like creating 
animation in HTML. ... JavaScript code is run on a 
browser only, while Java creates applications that run 
in a virtual machine or browser. Java is an OOP 
(object-oriented programming) language, and JavaScript is
specifically an OOP scripting language.
