Compiler — Angular Technical Interview Questions & Answers

Compiler

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.

Compiler — working 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.
