Google, the company whose code of conduct begins with the words “Don’t be evil,” has uploaded a new video to its developer channel talking about its programming language Dart, which Google calls its “evil plot to make it easier for you to build web apps.”

It’s a 40-minute video that talks about the programming language and its features.

“When we announced Dart, it kicked up a bit of a dust storm,” says Dart engineer Bob Nystrom in the YouTube description for the video. “In this talk, I discuss the challenges that Google and others face when building web apps today. I introduce Dart and show how its features were designed specifically to address some of those challenges.”

“You’ll see how Dart protects you from many of the dark corners and sharp edges of JavaScript and the DOM,” he adds. “When your programs grow and evolve over time, you’ll see how Dart can help keep your app nimble and maintainable. Thanks to Dart’s Dart to JavaScript compiler, you’ll see how you get all of that while still being able to run on any browser that supports modern JS and without the bad karma of fracturing the web.”
