Hoisting

“Hoisting” is an action performed by the JavaScript interpreter that moves function declarations of the form function foo() {}, and variable declarations of the form var foo; to the top of their containing scope. During this process, only the actual declarations are moved; any value assignments are left in the place where they were written.
