If you use WordPress in a professional way, you've probably come across Zac Gordon.

Zac is an enthusiastic and charming teacher who focuses on JavaScript in WordPress. He borrowed the phrase "Learn JavaScript Deeply" from Matt Mullenweg and he made it into his personal slogan. For the last several years, Zac has produced video classes, online conferences, live talks, and podcasts that focus on teaching you how to use Javascript in WordPress.

We recently partnered with Zac on a book, "React Explained". That book is available now. It's a fun and enjoyable introduction to React, which is the JavaScript framework of choice for WordPress, Drupal, Magento, and thousands of developers.
