Component Lifecycle
Component Lifecycle refers to the series of stages that a component goes through from its creation to its removal in a user interface framework or library, such as React, Angular, or Vue.js. It defines methods or hooks that developers can use to execute code at specific points, like initialization, updates, and cleanup, enabling control over behavior and performance optimization.
Developers should learn Component Lifecycle to manage side effects, optimize rendering, and handle resource cleanup in dynamic web applications, preventing memory leaks and improving user experience. It is essential when building interactive UIs with frameworks like React, where lifecycle methods (e.g., componentDidMount, useEffect) are used for data fetching, subscriptions, or DOM manipulations.
