Interpolation Event binding Property binding and Pipes

Interpolation {{ }} lets you render the property value as text; 

 <h3> {{ item.name }} </h3>

The interpolation syntax {{ }} :

<div *ngFor="let item of items">

 <h3> {{ item.name }} </h3>

</div>

Event binding lets your app respond to user input in the target environment by updating your application data.

Event binding ()  uses a set of parentheses, ( ), around the event, as in the following <button> element: 

<button (click)="share()">

Share

</button>

Property binding lets you interpolate values that are computed from your application data into the HTML.

property binding [ ] lets you use the property value in a template expression.

<a [title]="product.name + ' details'">

  {{ product.name }}

</a>

Pipes

Use pipes to display dates and currency values that are appropriate for a user's locale. Angular provides predefined pipes for common transformations, and you can also define your own pipes
