Method Source Code

/* Problem 2. Remove elements

 Write a function that removes all elements with a given value.
 Attach it to the array type./*from ww w.  j a v a 2 s .  com*/

 Read about prototype and how to attach methods.

 var arr = [1,2,1,4,1,3,4,1,111,3,2,1,'1'];
 arr.remove(1); //arr = [2,4,3,4,111,3,2,'1'];

var example = [1, 4, 5, 3, 6, 4, 7, 3, 2];

Array.prototype.remove = function(number){
    var editedArray = [],
        index;

    for (index = 0; index < this.length; index += 1) {
        if (this[index] != number) {
            editedArray.push(this[index]);
