What's wrong with var x = new Array();

if (!Number.prototype.toZeroPaddedString) {
  Number.prototype.toZeroPaddedString = function (count) {
    "use strict";
    var str = this.toString();
    return (new Array(count + 1 - str.length)).join('0') + str;
  };
}

I want my code to be clean by jsLint standards, however, I just cannot imagine how to get rid of this error given what I want to do.

Any advice?

Thanks.

Try this:

if (!Number.prototype.toZeroPaddedString) {
  Number.prototype.toZeroPaddedString = function (count) {
    "use strict";
    var str = this.toString();
    var ary = [];
    ary.length = count + 1 - str.length;
    return ary.join('0') + str;
  };
}
