I am a bit confused http://jsfiddle.net/
{ for (var counter = 1; counter < 6; counter++) { } } console.log(counter); If variables from loops are available in the scope the for loop is created, then why do I have access to the variable one level higher, since I created another scope by putting those brackets?
Variables created with the var keyword have function scope (or global scope if they're declared outside of a function).
ES6 introduces the let keyword for block scoped variables.
Loops do not have their own scopes.
A loop is a block, and blocks do not have their own scopes; variables created with var can only have function or global scope.
As others have pointed out, in ES6, you will be able to use block-scoped variables with the let keyword.
for(var counter = 1...), counter will be available from that point forward in the function containing this loop (or globally, if it is not in a function).You are wrong, loops do not have scopes.
