Interpolation

In Angular, interpolation is a technique that allows a component’s template to communicate with its corresponding component class. It allows you to bind a component’s template expression to a component’s property. For example, consider the following component:

import { Component } from '@angular/core';

@Component({
  selector: 'app-greeting',
  template: '<h1>Hello {{ name }}</h1>'
})
export class GreetingComponent {
  name = 'Fullstackadda';
}

Here, the name property of the GreetingComponent is bound to the template expression {{ name }}. When the component is rendered, the value of name will be interpolated into the template, resulting in the following HTML:

<h1>Hello John</h1>

Interpolation can be used to bind a component’s template to any property of the component class, including properties that are derived from other properties or values.

Some advantages of using interpolation in Angular are:

• It allows you to bind a template expression to a component property, making it easy to display dynamic data in the template.
• It is easy to use and requires minimal setup.
• It is a one-way data binding technique, meaning that data flows from the component class to the template, but not the other way around. This can help ensure that the component class is the single source of truth for the component’s data.
