export class ClickCounterComponent {
  clicks = 0;
  onClick() {
    this.clicks++;
  }
}

{{ clicks }}

  1. Step 1: Understand state increment

    The clicks property starts at 0 and increments by 1 on each click.

    After three clicks, clicks = 0 + 3 = 3.
  3. Final Answer:

Common Mistakes:
  • Forgetting to bind the click event properly
