Yes—avoid function calls in Angular template bindings such as: ```html {{ calculate() }} ``` They re-evaluate on every change detection cycle. Use Signals for state with a `computed()` signal instead: ```ts total = computed(() => this.price() * this.quantity()); ``` ```html {{ total() }} ``` A `computed()` signal caches until dependencies change. Pure pipes are another suitable option. Event handlers such as `(click)="save()"` are normal and aren’t the same performance concern.
