Hello!

Welcome to my blog, I’m a backend developer focusing at the moment on the .NET stack. I use this blog to document ideas or concepts I have learned or might be currently learning.

Go for the C# Developer - Multiple Return Values

I’ve been spending the last few weeks learning Go by reading Learning Go by Jon Bodner, so far I’ve been enjoying learning about Go, though there is still one thing I keep tripping over, in Go, you can return one or more values, for me Go is the first language that I have worked with that does that, in every other language I had to introduce a custom discriminating union to achieve what Go does natively....
