Javascript - Invert array position elements manually. I created this little code to my friends in Kwan

array_inverter.js

"use strict";
if (!Array.prototype.reverseOrder) {
  Array.prototype.invertir = function() {
    var inverted = [];
    for (var i = this.length - 1; i >= 0; i--) {
      inverted[this.length - (i + 1)] = this[i];
    }
    return inverted;
  }
}
var b = Array("1", "2", "3")
console.log(b.invertir());
