Making components, not controllers

- [Narrator] Now we move on to the second…video of this section and we are going…to use components instead of controllers.…First, we're going to take a look…at what components are since they…are a new feature in Angular 2…that was also added to Angular 1.5.…Which is why it's very important to use them in our code.…So next step would be to identify…where we can use components in our application…before actually creating those components.…What are components?…Well, a simple way to put it, is that…components are pieces of code that you would create…when a feature in your application…has to be used in different places.…

So basically, widgets with an HTML template,…a scope, and a controller.…Components also allow advanced DOM manipulation,…which in Angular 1 could be a way…to wrap JavaScript code like JQuery plugins…to make them compatible with…Angular change detection mechanism.…In our case, we're interested in components…because most of the code we're going to write…in Angular 2 will be components, so it makes sense…
