How to create your own react hooks.

React hooks may be excellent tools for encapsulating and reusing code in your components. The methods below explain how to create your own react hook:

1. Your Hook's Name: Pick a memorable name for your unique hook. To identify it as a hook, it should begin with "use" (following the React norm).
2. Create a Function: Write the logic of your custom hook in a JavaScript function. If required, this method can utilize other custom hooks in addition to built-in ones like useState and useEffect.
3. Define Parameters: If your hook requires any parameters, add them as arguments to your function.
4. Return Values: Your components should be able to use the values that the custom hook returns. Anything, including state variables, functions, or both, can be used as these values.
5. Example: To handle a counter, a custom hook named useCounter is used in the following straightforward example:

import { useState } from 'react';

  function useCounter(initialValue, step) {
  const [count, setCount] = useState(initialValue);
  const increment = () => {
  setCount(count + step);
  };

  const decrement = () => {
  setCount(count - step);
  };

  return { count, increment, decrement };
  }

Now, let's use this custom hook in a component:

import React from 'react';
import useCounter from './useCounter';
        
  function Counter() {
    const { count, increment, decrement } = useCounter(0, 1);
  
    return (
    <div>
    <p>Count: {count}</p>
    <button onClick={increment}>Increment</button>
    <button onClick={decrement}>Decrement</button>
    </div>
    );
  }
    
  export default Counter;

In this example:

UseCounter is a custom hook that contains the counter logic. To control the count state and its related functions, Counter is a component that makes use of the useCounter hook. Your component logic can be kept organized and reused across your application by building and utilizing custom hooks.
