[Practical React Programming] Revised Edition
A lecture based on this! 📖

This lecture is based on a book published in July 2020.
To keep up with the latest trends in rapidly evolving web technologies, keeping your course materials up to date is paramount.
I created this lecture based on Chapter 2 of the book [JavaScript with ES6+, Becoming an Attractive Language].
This lecture does not contain any React-related content, so even those who are not interested in React can listen comfortably.
