# Code Blocks

Code blocks are things that are bound by these curly brackets { and }.

# var
1- If you use var outside of a function, it          belongs to the global scope.

2- If you use var inside of a function, it          belongs to that function.

3- If you use var inside of a block, i.e. a for      loop, the variable is still available outside    of that block.
