Array.map method doesn't pass index and the array to the callback

[tedbeer]

Array.map must pass 3 arguments to the callback function: the current element, the current index and the array itself. But the current implementation passes only the first argument. Example:

var chars = ['a', 'b', 'c'];
chars.map(function( char, index, arr) {
 //do something
});
