What is ngZone, and how does it relate to Angular’s change detection? ● Angular uses NgZone to detect asynchronous events (like clicks, timers, HTTP). ● NgZone runs code inside Angular's zone, triggering change detection

utomatically.

• You can run code outside Angular's zone to prevent unnecessary change

detection.

✅ Example:

constructor(private ngZone: NgZone) {}

runHeavyTaskOutsideAngular() {

this.ngZone.runOutsideAngular(() => {

// code here won't trigger change detection

});

}
