I went over "Writing an Interpreter in Go" and "Writing a Compiler in Go" but instead of doing it in Go, I did it in C. In hindsight it was a very good decision, because it forced me to write the code myself, instead of mindlessly copying it. After finishing the books I've spent some time extending the compiler I've written and I've published it on github (https://github.com/kgabis/ape). I've read Bob Nystrom's previous book, so I'm sure Crafting Interpreters is great as well, but I really recommend Writing an Interpreter/Compiler in Go.

Shameless plug, but some time ago I've created a language where the main design goal was for it to be easy to use and embed: https://github.com/kgabis/ape.
