9. useEffectOnce()

Solution:

Here is one possible implementation using the useEffect() hook:

import { useEffect } from 'react';function useEffectOnce(effect) {  useEffect(effect, []);}

This implementation takes an effect function as an argument, and calls it with an empty dependency array []. This means that the effect will only run once, when the component is mounted.

Here's an example of how to use this hook:

import React from 'react';import { useEffectOnce } from './useEffectOnce';function MyComponent() {  useEffectOnce(() => {    console.log('Mounted!');  });  return (    <div>      <h1>Hello, world!</h1>    </div>  );}

In this example, the useEffectOnce() hook is used to log a message to the console when the component is mounted. The message will only be logged once, thanks to the useEffectOnce() hook.
