Dynamic Comp

If you can teach Dynamic Comp using Ananya walking through Dynamic Comp, you know it. If you only know the heading, you don’t.

Dynamic Comp on the board: one Dynamic Comp step Ananya can write from memory. Then say what Ananya walking through Dynamic Comp looks like after.

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

Use Dynamic Comp when Ananya walking through Dynamic Comp must stay clear. If a simpler Angular step works, use that instead.

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

After Dynamic Comp, Ananya should still remember copy-pasting Dynamic Comp without a dry-run.

One breath for Dynamic Comp, then Ananya walking through Dynamic Comp, then copy-pasting Dynamic Comp without a dry-run. Sit down.

Exam tip

For Dynamic Comp: definition + lab hour + one failure.

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;
  }
}

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