The code will output the following lines in the console:

• "render App"
• (after clicking the button once) "click", "render App", "render A"
• (after clicking the button twice) "click", "render App", "render A"
• (after clicking the button thrice) "click", "render App", "render A"

This is because the App component is rendered once initially, and then re-rendered every time the state is updated by clicking the button. The A component is also re-rendered every time the App component is re-rendered.
