Stoplight Exercise

As always, fork and clone this repo.

Part 1

Add JavaScript DOM event listeners to toggle the on/off state of three bulbs.

• When a user clicks on the "Stop" button, the top bulb should turn red.
• When a user clicks on the "Slow" button, the middle bulb should turn orange.
• When a user clicks on the "Go" button, the bottom bulb should turn green.

TIP: All three bulbs can be on/off independently of one another.

Part 2

Add new event listeners to log the mouse state of each button.

• When a user's mouse "enters" a button, log "Entered <textContent> button" to the console.
• When a user's mouse "leaves" a button, log "Left <textContent> button" to the console.

Bonus

Add one new event listener to log the state of each bulb.

• When a user clicks a button that just turned on, log"<textContent> bulb on" to the console.
• When a user clicks a button that just turned off, log"<textContent> bulb off" to the console.
