Animations

Animations is a Angular idea you prove with Arun walking through Animations, not with a slogan.

Do Animations once by hand. one Animations step Arun can write from memory. Change one input. Say the new result out loud.

Skip Animations and copy-pasting Animations without a dry-run shows up in lab hour.

Use Animations when Arun walking through Animations must stay clear. If a simpler Angular step works, use that instead.

Animations miss — copy-pasting Animations without a dry-run. Fix it before you talk about advanced Angular.

Animations is not a lonely heading. Arun ties it to Arun walking through Animations.

One breath for Animations, then Arun walking through Animations, then copy-pasting Animations without a dry-run. Sit down.

Exam tip

Board: Arun walking through Animations. Dry-run Animations. Name the trap: copy-pasting Animations without a dry-run.

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;
  }
}

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