Note: This is a short warm up question meant to help you familiarize with the coding workspace. Actual UI coding interview questions will be more complicated.
Make the text within the button display the number of times the button has been clicked.
This is a short question which only requires one state variable, which is the number of times the button has been clicked (count).
useState can be used to track that variable and replace the hardcoded 0 with the count state. Then attach an onClick handler on the <button> element and increment the count whenever it is clicked.
