$.each (array, function (index, value) {})
The callback function of the array is passed one index at a time and the corresponding array value as the parameter.
The callback function of the object passes one key-value pair at a time.

Returns a non-false equivalent to continue jumps out of the current iteration and goes to the next iteration.
