Unfortunately I get 3 warnings at jslint. Could someone please help?I already tried a lot, but didn't get it yet.Here's a jsfiddle: http://jsfiddle.net/KYjF9/21/JSlint options:/*jslint browser: true indent: 2 */ /*global $ jQuery alert*/ JavaScript:var Typing = function (el, toType, period) {  use strict;  this.toType = toType;  this.el = el;  this.loopNum = 0;  this.period = parseInt(period, 10) || 2000;  this.txt = '';  this.tick();  this.isDeleting = false;};Typing.prototype.tick = function () {  use strict;  var fullTxt = this.toType[this.loopNum % this.toType.length];  if (this.isDeleting) {    this.txt = fullTxt.substring(0, this.txt.length - 1);  } else {    this.txt = fullTxt.substring(0, this.txt.length + 1);  }  $(this.el).html('<span class=wrap>' + this.txt + '</span>');  var delta = 300 - Math.random() * 100;  if (this.isDeleting) { delta /= 2; }  if (!this.isDeleting && this.txt === fullTxt) {    delta = this.period;    this.isDeleting = true;  } else if (this.isDeleting && this.txt === '') {    this.isDeleting = false;    this.loopNum = this.loopNum + 1;    delta = 500;  }  setTimeout(this.tick.bind(this), delta);};var data = {  text: {    list: [hello, hallo, hola, what, ever],    period: 3000  }};$(document).ready(function () {  use strict;  var toType = data.text.list;  var period = data.text.period;  $(.js).each(function () {    if (toType) {      new Typing(this, toType, period);    }  });});
