1. We’re creating a variable called numItems and setting it equal to the number of items in the carousel.
2. We’re creating a variable called totalItemsWidth and setting it equal to the width of the carousel multiplied by the number of items in the carousel.
3. We’re creating a variable called totalWidth and setting it equal to the width of the carousel multiplied by the number of items in the carousel plus the width of the carousel.
