Logging the results of this function

Question

Somebody please explain me this code in detail

function reverse(s){
   return s.split("").reverse().join("");
}

It assumes the input to be a string. Given the input, the string is split using an empty string as delimiter. The result is an array, consisting of individual characters. Then, the reverse method of Array is used to reverse the order of the array's elements. Then, the string is concatenated again, using an empty string. — Rob W

Sorry all, I misunderstood the function. I thought reverse() is being called from the same function.. Thanks for answers. — Exception

The function takes a string, it splits it in its constituent characters to obtain an array using the split function, it reverses this array using the reverse method and joins the elements with an empty string.

Basically it reverses a string which given the name of the function I guess doesn't come as a surprise to anyone.

So:

reverse('abc')

will return:

cba
