Usage of Hooks

Hooks are special functions in React that allow you to use state and other React features without writing a class. This makes the code cleaner and more readable.

Firstly, hooks are used with function components, instead of classes. This simplifies the code structure, reducing complexity. For example:

import React, { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click here
      </button>
    </div>
  );
}

Notice how the ‘useState‘ Hook is used to manage the ‘count‘ state without the need for a class.

Additionally, hooks can be reused between components. This promotes code reuse and makes maintenance easier. For example:

import React, { useState } from 'react';

function useCounter(initialValue) {
  const [count, setCount] = useState(initialValue);

  const increment = () => {
    setCount(count + 1);
  };

  return [count, increment];
}

function Counter() {
  const [count, increment] = useCounter(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={increment}>
        Click here
      </button>
    </div>
  );
}

Here, the ‘useCounter‘ Hook is created and reused by the ‘Counter‘ component.

Therefore, hooks are a powerful tool in React component development, simplifying the code, promoting reuse, and improving readability.
