Tiny jQuery

Build a small DOM manipulation library that exposes a jQuery-like API.

Unit tests have been provided. They are written with the QUnit testing framework, and you can run them from the command line (see below), or by visiting the test/index.html file from a browser. To complete this task, get all the tests to pass!

Installing (optional)

You'll need Node.js (http://nodejs.org) and Grunt (http://gruntjs.com) if you want to lint your code and run the tests from the command line.

API

Select DOM elements:

var elems1 = $$(".selector #string > .here");
var elems2 = tQuery(".selector #string > .here");

Array-like API:

var spans = $$("span");

spans.length;  // Number, eg. 4
spans[0];      // DOM element
spans[3];      // DOM element
spans[4];      // undefined

Optional context specified as a second argument:

var elems = $$(".bob", document.getElementById("bocoup"));

Iteration over selection:

$$("div").forEach(function(elem, idx) {
  console.log("Element #" + idx + " in this selection: ", elem);
});
