Hi to whoever finds their way here,

This learning module React hooks is bugged.

The lesson will not pass despite having an identical solution to “view solution”

I’m sure this will be fixed soon as long as you report the bug.

import React, { useState, useEffect } from ‘react’;

export default function Counter() {

const [clickCount, setClickCount] = useState(0);

const increment = () => setClickCount((prev) => prev + 1);

useEffect(() => {

document.addEventListener(‘mousedown’, increment);

return () => {

document.removeEventListener(‘mousedown’, increment);

};

});

return (

<h1>Document Clicks: {clickCount}</h1>

);
