5 Lesser-Known React Hooks That Are Incredibly Useful

Beyond popular hooks like useState and useEffect, React offers other powerful hooks that can simplify specific tasks. Here are five lesser-known hooks and how to use them:

1. useId

What it does: Generates unique IDs for elements like labels or inputs, avoiding ID collisions.

When to use: In complex forms or reusable components.

Tip: Perfect for improving accessibility and preventing ID conflicts in large apps.

2. useDeferredValue

What it does: Delays updates to a value to avoid unnecessary re-renders during heavy interactions.

When to use: For real-time searches or large lists that might be slow to render.

Tip: Enhances user experience by smoothing updates in heavy UIs.

3. useLayoutEffect

What it does: Executes side effects synchronously before the DOM is painted.

When to use: When you need to measure or modify the DOM before it’s visible.

Tip: Use sparingly, as it can impact performance if overused.

4. useImperativeHandle

What it does: Customizes the instance of a ref in functional components.

When to use: To expose specific functions of a child component to its parent.

Tip: Avoid frequent use to keep your components simple and maintainable.

5. useDebugValue

What it does: Adds helpful information about a custom hook for the React DevTools.

When to use: In custom hooks that you often debug.

Tip: Useful for providing extra context when debugging complex custom hooks.

These lesser-known hooks are powerful tools for specific use cases, helping you write cleaner and more efficient code. Which one are you excited to try?
