In a previous blog post we explored how to perform immutable operations to update objects using Object.assign(). This time we are going to explore how to perform immutable operations on an array of objects which is a common pattern in Redux. If you wan’t to learn more about Redux, take a look at the excellent training course “Getting Started with Redux” by Dan Abramov, the creator of the library.

In this blog post we are going to cover a basic setup for working with Typescript and Typings in a Node environment. This is the starting point of many other post on this blog.

Avoiding mutations in our code is becoming increasingly important in Javascript due to the principles of functional that makes our code easier to predict and to scale. This blog post can be considered a continuation of a previous one: The Limits of Object.assign().

So, you have been using Object.assign to create copies of your objects right? Here’s a warning for you. Object.assign does not perform a deep copy.

Typescript is the new kid on the block, a newly attempt to bring order to the javascript chaos. ES6 is around the corner and is a fantastic step forward for frontend development (classes!) but it will take years to be fully implemented in all major browsers. That’s when Typescript comes to the rescue. Typescript goal is to be a superset of ES6 that, in addition to all the new stuff that the standard is defining, will add a static type system. Typescript has also a transpiler that converts our Typescript code (i.e. ES6 + types) to ES5 or ES3 javascript code so we can use it in today browsers.

In OOP, an abstract class cannot be instantiated, it serves only to provide common properties and functionality to child classes. In Angular, we have to make an analogy and define that an abstract directive is one that does not have a template or a link function, only a controller. The template is provided by child directives.
Continue reading “Abstract/Concrete Inheritance Model in AngularJS”Inheritance is a powerful way to extend directives functionality and at the same time, improve code reuse. Lets see how it works in Angular with a simple example. The first step is to create a directive called “outer” which is going to be our top-level directive in our hierarchy.
