Answer 2

A global variable is accessible from everywhere in the code.
This wouldn't be the cas if you define a variable inside a function.

// example for global var
var myvar1 = 'bla';
function foo1() {
console.log(myvar1);
}
foo1(); // prints 'bla'

// example local variable
function foo2() {
var myvar2 = 'bla';
console.log(myvar2);
}
foo2(); // prints 'bla'

BUT:

If you access myvar2 outside of foo2, it won't work:

console.log(myvar2); // doesn't print anything
