1You've wrapped the function in parentheses, creating an expression – adeneo Feb 11 '15 at 12:33

1You have a named function expression (see http://kangax.github.io/nfe/), and your sample will throw an error in any ES5-compliant environment. – Fabrício Matté Feb 11 '15 at 12:35

I'm not familiar with this syntax (exp); but JSHint shows 2 things : you forgot a semicolon at the end of the first line, and x is not defined, as it's not the same (or parent) scope. – enguerranws Feb 11 '15 at 12:36
