What Hacker News says?
Not a book, but I loved this series about building a Pascal interpreter (currently 12 parts): https://ruslanspivak.com/lsbasi-part1/ It was always on my bucket list to learn to write programming languages, but it's very daunting - this made it easy to learn in bite-sized chunks.

HN discussionThe "Let's Build A Simple Interpreter" series of posts (starting at https://ruslanspivak.com/lsbasi-part1/ ) is excellent, geared towards building an interpreter for a Pascal-like language in Python. It does not use a parser generator, and builds up everything incrementally. Unfortunately it's incomplete...

HN discussionhttps://ruslanspivak.com/lsbasi-part1/ you can continue with the links from there. do you want to target something in particular? implementing a lisp (scheme) or a forth is a good starting point.

HN discussionTrying to go through books about algorithms and data structures that use Python, might be a better approach. https://jovian.ai/learn/data-structures-and-algorithms-in-py... By the way, are you aware of the SICP Python version? https://wizardforcel.gitbooks.io/sicp-in-python/content/ When feeling more confident you can even try a go at something like doing a toy compiler. https://ruslanspivak.com/lsbasi-part1/ Or if…

HN discussionI've been following this tutorial recently and I've enjoyed it quite a bit. I think I understand grammars a little bit more as a result. If this style is interesting to you the author also has a series on building a web server from scratch. https://ruslanspivak.com/lsbaws-part1/

HN discussionIf you need some help for any info about initial Erlang ask me. For start: http://www.maht0x0r.net/library/computing/erlang.pdf http://www.erlang.org/erldoc http://rosettacode.org/wiki/Category:Erlang http://ruslanspivak.com/2007/09/09/erlang-for-python-program... and you need emacs24+ for good ide and programming with erlang or just use interactive shell erl for initial start.

HN discussionI know the author quite well. It all started with him following "Let’s Build A Simple Interpreter. Part 1." from Ruslan's blog ( https://ruslanspivak.com/lsbasi-part1/ ) where you are creating an interpreter for a pascal like language. He then decided to spit out some c64 assembler, and it has been a pretty cool journey after that :D

Discounting books, many other well written articles on JIT have been shared on HN over the years [0][1][2]; the one I particularly liked as it introduces the trinity in a concise way: Compiler, Interpreter, JIT https://nickdesaulniers.github.io/blog/2015/05/25/interprete... / https://archive.vn/HaFlQ (2015).
