Core Concepts of Angular 2 you must know
1. Must have a root component-
As read above, developing an application using this web development platform begins with defining a set of components; it is to be kept in mind that every application must have a root component. This gives a tree-like structure to the application.
2. Different components in Angular 2 are-
Directives: [FormattedRating, WatchButton, RateButton],
@Input () talk: Talk;
@Output () rate: EventEmitter;
3. Input and Output Properties-
The setting of the input properties can be done with property bindings, i.e., using square brackets. Whereas, in case of the environment of output properties, subscribing to them using event bindings with the use of parenthesis helps.
4. The template describes component rendering on the page-
It requires to know the list of directives to be used in the template. Directives make the pillars of this web development framework and are self-describing. They describe private API, lifecycle hooks and know the ways of interacting with the host element.
5. Dependency Injection-
If the framework has a service-dependent component, then there is no need for the creation of that particular service. The framework provides the service which you would have requested the constructor, which also helps in increasing dependency on the interfaces rather than concrete types. The result is getting decoupled code enabling testability etc.
6. Single API in both Angular JS and Angular 2-
Angular 2 have dependency injection modules providing a single API. This also implies that the API used to inject global dependencies into the component can be used for local dependencies as well.
7. Property Bindings-
Property bindings used in the web development framework help in syncing up the DOM with the component tree and the component tree with the model. When the VM turn ends, every component of the component tress is checked along with the property bindings, and then the elements and DOM are updated.
No, no output properties of a component are updated using property bindings.
Angular 2 is smarter than its predecessor in the sense that it knows the correct time to run the check which removes the need of calling scope.$ to apply, it is done automatically unlike in Angular 1. The framework recognizes when to integrate with the 3rd party libraries without getting the call manually.
