Intuitive AngularJS testing with Jasmine

Detect HTML5/CSS3 Features Using the Modernizr JavaScript Library

In the past, when we developed an application or website, there was a limited variety of browsers: Microsoft Internet Explorer and Netscape. The changes between the browsers forced the developers to detect the browser type by user string and load the appropriate JavaScript file accordingly.

 

Now there are a huge variety of browsers— five major desktop browsers—and countless browsers on other platforms, including mobile and gaming consoles. Now that you have an image of all the different browsers that we come into contact with daily, remember that almost all the major browsers update frequently.  Each of these updates affect (sometimes heavily)  the features that the browser supports.

 

In this post we will share how to use the Modernizr library in order to solve this mess...

What goes around comes around (Javascript testing with Jasmine and Karma)

My team uses AngularJS which was written with testing in mind “so there is no excuse for not testing”.

The dependency injection mechanism it uses is powerful for substituting real dependencies with fake ones for testing in isolation.

Separation of concerns is also inherent in the framework, so that logical code is tested separately from presentation logic.

 

Our chosen testing framework is Jasmine and we use the spectacular test runner for Javascript - Karma.

JavaScript Inheritance Revisited - part 2

The second part of the JavaScript Inheritance Revisited blog post

This post focuses on what other frameworks and compiled-to-js languages are doing in terms of inheritance.

JavaScript Inheritance Revisited

JavaScript is an excellent language for Object Oriented programming although its prototypical inheritance mechanism is often misunderstood. Alex Sexton (@slexaxton) recently posted a nice (and somewhat amusing)blog post called "Understanding JavaScript Inheritance" which gives a fresh and interesting view on the whole topic. There are numerous other articles, blog posts, etc., available around this topic. Most of them explain various ways to implement JavaScript inheritance (e.g. this and the famous one by John Resig here). The problem, as far as I can see it, is that as a newbie JavaScript developer one might be lost in the slew of the specific details that each and every such post presents. In this blog post I want to try a different approach where I create a general overview of the various methodologies without naming them with specific names (such as "Functional", "Pseudoclassical", "Pseudoclassifunctional", or "Jerry"). I hope that after reading this blog post you will be able to understand the best direction to take with your inheritance scheme.

CSS is dead, long live SASS

Any developer that has written some CSS probably knows the hard, sad, truth: CSS is ugly. Not only is it ugly,but it is very hard to maintain and change. CSS was the big promise of the early '00 - no more tables and HTML attributes - just add some CSS to classes and ID and style your HTML neatly with clear separation between content and design. Unfortunately that just hasn't happend.

 

Keep reading to find out what SASS stands for and what it means for you.
