JavaScript - testing tools: Jasmine (BDD), JsUnit, Karma (test runner)

1. Jasmine http://jasmine.github.io/ is the priority for testing, due to its BDD approach. 
2. JsUnit is an option (w/o BDD):http://www.jsunit.net/
3. Karma http://karma-runner.github.io/0.12/index.html - it is JavaScript test runner.

AngularJS + Bootstrap best practice

The main point: with AngularJS use pure CSS Bootstrap (don't use BootstrapJS)

JavaScript - shuffle an array, mix up array elements randomly

Mix up (shuffle) array JavaScript function is taken from here:
Fisher–Yates Shuffle http://bost.ocks.org/mike/shuffle/
function shuffle(array) {
  var m = array.length, t, i;

  // While there remain elements to shuffle…
  while (m) {

    // Pick a remaining element…
    i = Math.floor(Math.random() * m--);

    // And swap it with the current element.
    t = array[m];
    array[m] = array[i];
    array[i] = t;
  }

  return array;
}

JavaScript D3 - random integer number

Decimal values are fine, but if you ever need whole numbers, you can use JavaScript’s Math.round() method. For example, you could wrap the random number generator from this line

    var newNumber = Math.random() * 30;

as follows:

    var newNumber = Math.round(Math.random() * 30);

Example:

d3.selectAll("p").style("color", function() { return "hsl(" + Math.round(Math.random() * 360) + ",100%,50%)"; });
