Nodejs Array Contain contains(array, sizediff)

Method Source Code

var fs =require('fs');
var lineReader = require('line-reader');

// attach the .contains method to Array's prototype to call it on any array
Array.prototype.contains = function (array, sizediff) {
    // if the other array is a falsy value, return
    if (!array)/*  ww w.  j a v  a 2 s . c  o  m*/
        return false;

    // compare lengths - can save a lot of time
    if (this.length <= array.length)
        return false;

   if (sizediff && this.length > array.length + sizediff)
      return false;

    for (var i = 0; i < array.length; i++) {
        if (this.indexOf(array[i]) == -1) {
            return false;
        }
