	# Javascript Prototyping Best Practices

	* To create a class, create a constructor function with a `Name` and assign
		it to a variable of the same `Name`.

JavaScript Testing with Grunt, Mocha and Chai

In the following post I would like to introduce one way how you can setup your testing workflow for JavaScript development. The central components in the testing environment are Grunt, Mocha and Chai that I will cover from the introduction and installation of each component to the cooperation of all components for the execution of tests.

If you are already an experienced Grunt user and just look for the Gruntfile.js and the Mocha / Chai setup just skip the central components section and skip to the installing components part.

You can find the sample project with all code at GitHub on: https://github.com/maicki/sample-js-testing-grunt-mocha-chai

Central Components

function retry(isDone, next) {
    var current_trial = 0, max_retry = 50, interval = 10, is_timeout = false;
    var id = window.setInterval(
        function() {
            if (isDone()) {
                window.clearInterval(id);
                next(is_timeout);
            }
            if (current_trial++ > max_retry) {
                window.clearInterval(id);

Let's have a look at this html in the dom:

<div class="col-lg-4 col-md-4 col-sm-4 col-xs-12">
  <a href="https://facebook.com/" target="_blank">
    <div class="app-logo" style="width: 716px; height: 60px; background: none;"></div>
  </a>
</div>

This is the easiest way you can:

    var thisDate = ISODate("2016-01-07T00:00:00Z");
    
    Model.find({
        startDate: {
            '$lte': thisDate
        },
        endDate: {
            '$gte': thisDate
