Javascript array reverse function unexpected behavior

Question

I would like to understand why situation 1 and situation 2 don\'t return the same results.

Situation 1 :

var array1 = [\"1\", \"2\", \"3\"];
var arra         


        

Answer 1

The reverse method transposes the elements of the calling array object in place, mutating the array, and returning a reference to the array. Thus, it does not return the reversed array.

CHECK the manuel. https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/reverse
