var GlobalVariable;
function iRock() {
    var myScopeVariable = 'foo'
}

Basically a global variable can be used by any function, method or anything in the file. While a variable inside a function only exist within it's scope or curly braces as you can imagine.

Let me know if you still didn't get it
