Create a Review carousel – JavaScript Project
You will learn how to make a carousel of reviews using a button that creates random reviews in this lesson. We will use HTML, CSS & JavaScript to create this project.
This is a useful tool to have for displaying client reviews on a personal portfolio or an e-commerce website.
JavaScript Fundamentals will be covered in this project:
- objects
- DOMContentLoaded
- addEventListener()
- array.length
- textContent
