+This course provides a comprehensive but concise introduction to the best practices of React front-end development and React Native mobile development. It focuses on the latest versions of React and React Native and is updated every semester. It is a valuable resource for tackling the complexities of front-end development.
 
 The course also offers a good training ground. Be prepared for a significant workload throughout the semester. If you are unsure about how to write React code when doing homework, I recommend spending extra time carefully reading the relevant chapters on react.dev before diving in.
