3. React re-render 3

The code will output the following by console.log:

A
B
C
App
D

Explanation:

• When <App/> is rendered, the useEffect hook runs and setState is called, causing a re-render.
• During the re-render, console.log('App') is called and <A><B/></A> and <D/> are rendered.
• <A> is rendered first, calling console.log('A'), and then <B> is rendered inside of it, calling console.log('B').
• Next, <C> is rendered inside of <B>, calling console.log('C').
• Finally, <D> is rendered outside of <A>, calling console.log('D').
