Hello awesome people👋, welcome back!

This is again a super simple post about Angular, but pretty informative and you might have not read about it so far.

Let's begin.

What is Text Interpolation?

Interpolation refers to embedding expressions or just variables into marked-up text in the Angular app.

By default, interpolation uses the double curly braces {{ and }} as delimiters.

app.component.ts

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'Hello World';
}

app.component.html

<!-- Hello World! -->
<span>{{ title }}!</span>

Let's change the default delimiters to Starstruck emoji 🤩

Angular allows to change the default delimiters {{ and }} to custom symbols/emojis.

All you need to do is add the interpolation option to @Component decorator in your App HTML (app.component.html) with custom start and end delimiters.

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
  interpolation: ['🤩', '🤩'],
})
export class AppComponent {
  title = 'Hello World';
}
  <!-- Hello World! -->
  <span>🤩 title 🤩!</span>
