import { useEffect, useLayoutEffect } from 'react'; export default function App() { console.log('1'); useEffect(() => { console.log('2'); }, []); useLayoutEffect(() => { console.log('3'); }, []); return <div>BCraft</div>; }

In this React component, the order of output to the console will be as follows:

1. The body of the component function executes first, so 1 is logged.
2. Then useLayoutEffect is called, which runs synchronously after all DOM changes but before the browser repaints. Therefore, 3 is logged.
3. After the component is rendered, useEffect is called, which runs asynchronously, so 2 is logged.

The final order in the console:

1
3
2

This is because useLayoutEffect blocks the painting until its code executes, whereas useEffect runs after the painting.
