An introduction to Feature Policy
Feature Policy allows web developers to selectively enable, disable and modify the behaviour of certain APIs and web features in the browser. It's like Content Security Policy but instead of controlling security, it controls features!
Page Visibility API

Notable Podcasts
Marie and Chris talk about how they decide what new features get added to CodePen, and get into the process of taking them from a "lightbulb moment" to building them out on the app.
