Counter Solution

This is a short question which only requires one state variable, which is the number of times the button has been clicked (count).

Declare count as a variable. Attach a callback on <button>'s on:click handler and increment count value within it. count will now be incremented whenever <button> is clicked.

Test Cases

  • Click on the counter to increment the count value by one.
  • Click multiple times and check that the count value increases on each click.
