Angular lifecycle hooks explained

Lifecycle hooks in Angular provide a way to execute custom code during specific lifecycle events of a component or directive, allowing developers to better manage application behavior. These hooks, prefixed with "ng," include those for both standalone components and those with child components, such as OnChanges, OnInit, DoCheck, and OnDestroy, among others. They serve various purposes, such as initializing data, cleaning up resources, and performing custom change detection. The hooks are called in a specific order, which aligns with Angular's phases of bootstrapping and change detection, and developers can use interfaces like OnInit or DoCheck to hook into these events. Using lifecycle hooks effectively can enhance component functionality, optimize performance, and manage resources efficiently, especially when dealing with asynchronous operations or complex DOM manipulations. The article provides in-depth explanations and examples of how these hooks work and how to implement them in Angular applications, emphasizing best practices like immutability and proper cleanup to ensure performance and prevent memory leaks.
