Introduction to Angular Lifecycle Hooks

Welcome to this comprehensive exploration of Angular components and their lifecycle. In this video, we will take an in-depth look at the critical concept of lifecycle hooks in Angular. Understanding these hooks is essential for building efficient, maintainable, and predictable Angular applications. Whether you are a beginner or an experienced developer, mastering lifecycle hooks will enhance your ability to respond to component events like creation, updates, and destruction effectively.

We will begin with a clear Recap - What Are Lifecycle Hooks? to ensure you grasp their purpose and significance. Then, we'll walk through The Lifecycle Flow Overview to familiarize you with the sequence of lifecycle events and when they occur during a component's life. This sets the foundation for understanding each specific hook, including ngOnChanges, ngOnInit, ngDoCheck, ngAfterContentInit, ngAfterContentChecked, ngAfterViewInit, ngAfterViewChecked, and ngOnDestroy.

Throughout the video, you'll learn about the purpose of each lifecycle hook, see practical examples, and discover best practices for their use. We will also cover a Practical Example Summary that illustrates how to manage resources and subscriptions efficiently, highlighting the importance of cleanup in ngOnDestroy. By the end of this session, you will know exactly how and when to utilize each hook to improve your Angular projects.
