What is Angular 2.0?

After the tremendous success of the Angular 1.3, there was still a need to develop something which worked better and covered up almost every flaw that the angular 1.3 couldn’t make up to. Considering this, the Angular 2.0 came into the picture and ever since it was launched, it has remained a favorite of developers.

So if you are a developer thinking to get an Angular 2.0 online certification, you should know that it is a framework that works on JavaScript and is used majorly to create web based applications. An important thing to understand here is that the Angular 2.0 is nothing sort of the MVC as it is something that more of relies on being a framework that is component based.


The Angular 2.0 is a framework that allows the developers to work with the three major concepts of it. These concepts include:

Ø  Components

The first thing you ought to do while creating a web application using the Angular 2.0 is to define all the basic components. These components could be of the UI, screen as well as the route to be used. This can more easily be defined as creating a component tree. The tree would have one most important component which will be known as the root component and then branches and sub-branches.

Since there are a lot of inbuilt properties, all you need to do is the basic defining and most of the work would automatically get sorted for you. Each of the components that you define will have inputs and outputs, lifecycles and would be self-describing in nature.

Ø  Dependency Injections

To make it simple for the developers, the Angular 2.0 comes with a fixed list of predefined dependency injection module. Understand what a dependency injection can be simply defined. Just like a component needs to have a service to depend upon, this service is created with the help of the dependency injections. As soon as you request for the service, the constructor would request the Angular 2.0 framework to define it for you.

For someone who doesn’t know a lot about the Angular won’t see much of the use of the dependency injections until you start using it. In your Angular 2.0 online training in Houston, you’ll be taught how it helps in making the apps better especially when they are bigger in sizes.

Ø  Bindings

Also known as the property bindings, the main use of this concept of the Angular 2.0 is to create a basic level of synchronization between the different components of the component tree with the DOM and the basic model respectively. As soon as you make a basic change to the components, it will get adopted all across the app and thus reduce the work of doing everything at different levels manually. This change can be reflected only with the help of bindings.

The zones are another important component of the bindings that are used to set the time frames as to when to use bindings and lead to automatic changes.
