In this week's episode, I'm delighted to welcome back Zac Gordon. If you spend any time in the WordPress world, you've probably come across Zac. He's a really enthusiastic and charming teacher who specializes in JavaScript for WordPress. He's done video classes, online conferences, live talks, podcasts, video casts, you name it. He's been out there trying to teach people how to use JavaScript, particularly in the WordPress context. For the first time, he's written a book, and he did it with OSTraining. React Explained is available now, and it teaches you how to use the React framework, which is increasingly popular in WordPress, but also Drupal, Magento, and other platforms. We talk with Zac about his background, his love of yoga, and also about why he decided to focus on React for his first book.
