What is useDebounce?

The useDebounce hook in React is a handy tool for delaying the execution of a function or state update until a specified time period has passed without any further changes to the input value. This is particularly useful in scenarios like handling user input or triggering network requests, where it helps reduce unnecessary computations and ensures that resource-intensive operations are only performed after a pause in the input activity.

How to Use useDebounce in React?

Here are some step to use it:

1. Install useDebounce package library

  npm install use-debounce

2. Import useDebounce as a hook:

import React, { useState } from "react";
import { useDebounce } from "use-debounce";

export default function App() {
  const [text, setText] = useState("Hello");
  const [debouncedValue] = useDebounce(text, 300);

  return (
    <div>
      <input defaultValue={"Hello"} onChange={(e) => setText(e.target.value)} />
      <p>Actual value: {text}</p>
      <p>Debounced value: {debouncedValue}</p>
    </div>
  );
}

  const [debouncedValue] = useDebounce(text, 300);

• parameters:

  1. value: any the value that you want to debounce. This can be of any type.
  2. delay: number The delay time in milliseconds. After this amount of time, the latest value is used.

Finally, This helps prevent unnecessary updates and optimizes performance.
