Innovative JavaScript function improvement
Often I see interview question/answers for upgrade myself, one of questions was: how you could write a function to make a deep array flat?
example:
var array = [1,[2],[3,[4,[5,[7,[8]]]]],[6]];
The interviewer answer it like down code:
var res = array.toString().split(',');
But the SO doesn't accept it, why? it works awesome and the interviewer doesn't use flatten function of new JavaScript.

If you would tell the interviewer why this thing works the way it works...especially the toString() part, then you're very good to go. Because, as you will start explaining toString() you will realize this method is called by each child element in a recursive fashion, just like in an actual solution.

The solution provided doesn't work in the following case:
var array = ["abc",["def,ghi"]];
var res = array.toString().split(',');
You'd get an array of 3 elements instead of 2. The question doesn't make any assumptions over the type of the values.
