Debouncing vs. Throttling: The Ultimate Guide to Mastering Performance Optimization in JavaScript!

What Is Debouncing?
Debouncing ensures that a function executes only once after a specified delay. This is particularly useful in scenarios where a user performs rapid actions, like typing in a search box or resizing a window.

How It Works:
The timer resets with each event. Only after a certain delay with no new events does the function execute.

Common Use Cases for Debouncing:
1. Search bar suggestions (execute after the user has stopped typing).
2. API calls for user input.
3. Auto-saving form inputs.

What Is Throttling?
Throttling ensures that a function executes at regular intervals, regardless of how often the event fires. This is ideal for events that occur continuously, like scrolling or mouse movement.

How It Works:
Even if events keep firing, throttling enforces a limit on execution frequency. This keeps your application responsive without overwhelming the browser.

Common Use Cases for Throttling:
1. Handling scroll events (e.g., infinite scroll).
2. Updating a progress bar as a user scrolls.
3. Monitoring real-time resizing of elements.
