Kudos to the brilliant practical book!

The author walks you through the process of writing an interpreter step by step following the test-driven approach. He writes in pure Go with clear syntax. He provides sufficient explanation without overwhelming with details. The goal is to get your feet wet by having done a simple interpreter.

I was in doubt when he chose to write an interpreter for his invented language. But it turned out this approach would pave the way for you to write your own simple language.

After finishing the book, I'm confident to write an interpreter for any common language.
