JavaScript has grown a lot in recent years, and nowadays allows developers to create extremely dynamic and rich client-side Web applications. This course leads you through the latest JavaScript syntax. The course also introduces some of the more commonly used libraries such as Jest for testing, and Axios for API invocation. Students will also be introduced to the popular ReactJS framework (other frameworks such as Angular or Vue can be used instead).
