ChatGPT stories are everywhere. The conversational chat API by OpenAI let users feel enthusiastic about AI advancing so fast, specifically after playing with Dall-E, StableDiffusion, and others most recently.

I have asked ChatGPT ”Write a simple React Hook”, after I heard that ChatGPT could improve coding. The following part is written by OpenAI’s new star.

A simple React hook is a function that allows a React component to use state and other React features without writing a class. Here’s an example of a simple React hook that uses the useState hook to add state to a functional component:

import { useState } from 'react';
function useCounter() {
const [count, setCount] = useState(0);
function increment() {
setCount(prevCount => prevCount + 1);
}
function decrement() {
setCount(prevCount => prevCount - 1);
}
return { count, increment, decrement };
}
export default useCounter;

This hook allows a functional component to keep track of a count and increment or decrement the count as needed. To use this hook in a functional component, you would import it and call it inside the component’s body like this:

import useCounter from './useCounter';
function MyComponent() {
const { count, increment, decrement } = useCounter();
return (
<div>
<p>{count}</p>
<button onClick={increment}>+</button>
<button onClick={decrement}>-</button>
</div>
);
}

In this example, the functional component uses the useCounter hook to add state and the increment and decrement functions to the component, allowing it to keep track of a count and update the count when the user clicks the + or - buttons.
