Angular Interview Practice

The component lifecycle in Angular indeed refers to the sequence of events that occur from the moment a component is created, through its active use, and eventually to its destruction. This lifecycle encompasses various phases such as initialization, change detection, and final cleanup, during which Angular provides specific hooks that allow developers to tap into these phases and perform custom logic at each stage.

For instance, when a component is initialized, the ngOnInit lifecycle hook is invoked, allowing developers to perform any necessary setup work, such as fetching data. Similarly, the ngOnDestroy hook is called just before a component is disposed of, which is an ideal place to clean up subscriptions or timers to prevent memory leaks.

This focus on creation and destruction makes the component lifecycle crucial for managing resources efficiently and ensuring optimal performance within an Angular application. The other choices, while relevant to Angular development, do not directly address the explicit phases through which a component passes during its existence, making the selected answer the most accurate reflection of what the component lifecycle encompasses.
