You don't understand _any_ of it?

Here you're assigning to 'var'. You're not in a function, so 'var' is a
global variable.

Here you're assigning to 'var'. If you assign to a variable anywhere in
a function, and you don't say that that variable is global, then it's
treated as being local to that function, and completely unrelated to
any other variable outside that function.

Here you're assigning to 'var', but this time you've declared that it's
global, so you're assigning to the global variable called 'var'.
