Building a Grocery List App with React
React is one of the most popular front-end web development frameworks in the world and something worth knowing a little about. It provides a declarative and composable interface to make building user interfaces with complex interactions more manageable. In this hands-on lab, we'll go through building a simple grocery shopping list application from start to finish. To feel comfortable completing this lab, you'll need to know how to do the following: - Create a new React application. - Utilize state and props within React components. - Handle browser events using React components. If you're currently unsure of how to perform any of these actions, consider taking the short **Expanding Your JS Skills with React** course to get up to speed.
