WTF is a type switch in

In this video, we'll learn what a type switch is and how to use it in Go. We'll use this knowledge to create a simple example program that demonstrates how to use a type switch.
If you're new to programming, or if you just don't understand type switches very well, this video is for you! By the end of this video, you'll be able to use type switches to control the type of data that flows into and out of a Go program. So check it out, and let us teach you something new!

These are the times when I feel like I want proper enums in Go. There is Go proposal for proper enums in Go, but there is no consensus from the team or the community. For now, there is "enumer" utility (designed following Rob Pike's "stringer" utility) that scaffolds/generates the boilerplate that you just typed in this video. 🙂

I agree. Ive resorted to using specially named constants but it’s not the same.

Nice content dude! As a general rule, to make your code more flexible and to explicitly declare what functionality is being used, your functions should accept interfaces and return structs. Exception to this is returning the error interface
