Compiler

Compiler is a Angular topic. In plain words you use it for a short Compiler example in a campus SPA. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Compiler example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Compiler.

From the example next to this theory — Compiler: toggle open.

Trap — only saying “Compiler” with no example. Fix that before you talk about advanced Angular.

Viva — what is Compiler? Then show the smallest Compiler example you can type. Then name the trap.

Exam tip

What is Compiler? Show this: the smallest Compiler example you can type. Trap: only saying “Compiler” with no example.

Example

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

@Component({
  selector: "app-root",
  template: `
    <h1>{{ title }}</h1>
    <button (click)="toggle()">Toggle</button>
    <p *ngIf="open">Panel open</p>
  `,
})
export class AppComponent {
  title = "Angular practice";
  open = true;
  toggle() {
    this.open = !this.open;
  }
}

Compiler: toggle open. Say whether the panel is on screen after one click.
