Let's be honest, we don't all do TDD nearly as much as we think we should. In this article Simon takes a good look at 12 benefits of following a test-driven development approach to your coding projects.

In this article we're going to talk about how to write a Jasmine unit test to validate the values of a promise returned from an Angular factory. It's not as complicated as it sounds!

Arrow functions are a new addition to the latest iteration of JavaScript (ES2015). They allow developers to write more terse functions (i.e. fewer lines of code) but there's also a major difference between a standard JavaScript function expression and an arrow function: a reference to this is not being created for every new function definition. Let's take a look at a bit more in detail and see what this means.

As mentioned in an earlier post AngularJS has some services that use Promises (like $http) and there are other ways that you can utilise promises within your AngularJS application.

AngularJS can utilise promises in its routing via a property called 'resolved'. The resolve property guarantees that a particular route is going to be loaded only when a promise is successfully fulfilled (resolved).

Promises (or Futures if you’ve been following the JavaScript news in the past) are allowing developers to write synchronous code in an asynchronous fashion. Before we get to AngularJS specific discussion on promises first, let’s discuss promises that come natively with JavaScript. (Refer to this table to see which browsers have native Promises implementation)

In this article we take a deep look at how to work with the event emitters and listeners in AngularJS, covering $broadcast, $emit, $on and the importance of scope hierarchy.

The bane of my life has always been validating forms. Checking for X number of characters or numbers, making sure fields are all filled out, adding regular expressions to these checks, applying if and switch statements to these checks was never something I enjoyed doing. Maybe the developers behind Angular shared similar sentiments as they have come up with quite a few number of built in validation features for working with forms in Angular.

People who are new to AngularJS often ask this question - what is the difference between ng-show / ng-hide and ng-if. Although seemingly these directives work in the same way there is a significant and important difference between them.

AngularJS comes with a list of built-in filters that allows developers to modify bound values within the view template. The official description states that a filter "selects a subset of times from array and returns it as a new array".
