Components will appear here as they render.
Use the Hook Lab to trigger events.
Start in the Hook Lab below
Pick a hook tab (useState, useReducer, etc.), click a button, then watch this timeline fill with color-coded events showing exactly what React did.
Clicking +1 or -1 calls setState. This causes CounterState to re-render.
Watch: Timeline: blue "state" block (setState call) then amber "render" block (re-render).
Last event
Events will show here after you interact with the Hook Lab.
