Lifecycle methods or hooks in frontend frameworks play a crucial role in managing the behavior and state of components throughout their lifecycle, allowing developers to perform actions at specific stages such as component creation, updates, and removal.

Lifecycle methods or hooks are timed methods that help manage the effects of change detection in frontend frameworks . They are used to control a component's behavior and perform specific actions at different stages of its lifecycle ². Here are some lifecycle hooks used in Angular and React:

- ngOnChanges: Fires when the @Input bound class members are modified.

- ngOnInit: Fires once upon initialization of a component’s input-bound (@Input) properties.

- ngDoCheck: Fires with every change detection cycle.

- ngAfterContentInit: Fires after the component’s content DOM initializes (loads for the first time).

- ngAfterContentChecked: Fires after every cycle of change detection targeting the content DOM.

- ngAfterViewInit: Fires once after the view DOM finishes initializing.

- ngAfterViewChecked: Fires after any change detection cycle targeting the component’s view.

- ngOnDestroy: Fires upon a component’s removal from the view and subsequent DOM.

- constructor(): Called when the component is first created.

- render(): Responsible for generating the component’s virtual DOM representation based on its current props and state.

- getDerivedStateFromProps(): Invoked during the mounting and updating phase of a component.
