Interfaces are everywhere in Go. The basic error type is an interface, writing with the fmt package means you are probably using an interface, and there are countless other instances where they pop up. In this episode Mark, Mat, Johnny, and Jon discuss interfaces at length, exploring what they are, how they are using them in their own projects, as well as tips for how you can leverage them in your own code.
