Introduction to React

In this 3-day Introduction to React training class, students learn the fundamental ideas behind React and then quickly move on to hands-on problem solving and some of the most advanced and up-to-date techniques in React development, including: Redux, Redux thunk, Redux Saga, and server-side react. The course teaches just enough about testing and tools for students to be productive, but is primarily focused on hands-on exercises in which students will build a real-world ecommerce shopping cart application.

This course is designed for experienced professional developers (in any language) who want to learn how to quickly become productive with the latest version of React.
