### Learning Objectives

- [ ] Develop a web app according to a specification
- [ ] Combine concepts covered in previous exercises

### Why are we doing this?

These challenges are designed to develop your problem-solving skills.

In this exercise you will build an app which shows one image at a time from a collection. It must meet the criteria below:

#### Acceptance criteria

- [ ] Given a web page with a carousel of images
When the page loads
Then the first image in the carousel should be displayed

- [ ] Given forward and back buttons
When the forward button is clicked
Then the next image in the carousel should be displayed
And
When the back button is clicked
Then the previous image in the carousel should be displayed

- [ ] Given at least 4 images in the carousel
When the user reaches the end of the carousel in either direction
Then the carousel should loop back to the first/last image

#### Advanced stretch functionality

- [ ] Given auto-forward and auto-back buttons
When the auto-forward button is clicked
Then the images should automatically advance every 5 seconds

- [ ] When the auto-back button is clicked
Then the images should automatically go back every 5 seconds

- [ ] Given the carousel is auto-advancing (in either direction)
When the stop button is clicked
Then the auto-advance/go back should stop

- [ ] Given the carousel is auto-advancing (in either direction)
When the forward button is clicked
Then the auto-advance should stop
And the next image should show
(next = stop + forward)

- [ ] Given the carousel is auto-advancing (in either direction)
When the back button is clicked
Then the auto-advance should stop
And the previous image should show
(back = stop + back)
