I don’t know what’s ahead for web development, and I couldn’t change it if I did. What I do know is that I want more than this for us. I want more than this for you. I may not know what happens next, but I know that I can help you be ready for it. So I’m not done. wil.to/js4e/newslet...

Josh's Whimsical Animations course is INCREDIBLE. It contains all of the amazing tricks that he's curated over the years, for you to install onto your own brains. e.g., I went from having no knowledge of the Canvas API to being able to create snazzy animations like these fireworks from scratch.
