In Vue.js, executing custom code at specific times during a component’s lifecycle is essential for building dynamic and responsive applications. Vue provides lifecycle hooks—special methods that allow you to run code at precise moments such as when a component is created, mounted, updated, or destroyed. Using these hooks effectively helps you manage data fetching, event listeners, and cleanup tasks, ensuring your app runs smoothly and efficiently. Understanding how to execute custom code at the right time is important because:
-
Optimizes app performance: Run code only when necessary, avoiding unnecessary computations.
-
Improves user experience: Load data or trigger animations at the right moments.
-
Ensures resource management: Properly initialize and clean up resources like timers or API calls.
-
Supports modular code: Organize your logic based on the component’s state and lifecycle.
