## Part 1
|
|
|
|
|
|
Add 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 DOM 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.
|
|
|
|
|
|
**TIP:** Each event type will need a separate event listener.
|

## Bonus
|
|
|
|
|
|
Add **one** new DOM 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.
|
|
|
|
|
|
**TIP:** A click on only a button should cause a message to be logged to the console.
