What is JavaScript?
JavaScript is a scripting or programming language that allows you to implement complex things on web pages — every time a web page does more than just sit there and display static information for you to look at — displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc. — you can bet that JavaScript is probably involved.[1] </blockque>
Variables
A variable is a container for some value. Like a number to be used in a sum, or a text string.
Most importantly: variables' values can change. They aren't the values themselves, but containers for values, like little boxes that you can store things in.
