The best resource for any new/amateur compiler writer who doesn't want to deal with code-gen (and even for people who eventually do want to do code-gen) is Bob Noystrom's Crafting Interpreters: https://www.craftinginterpreters.com/ https://www.craftinginterpreters.com/ It is well paced, well illustrated, and demonstrates a very simple recursive descent parser, avoiding all the junk typically foisted on students. I cannot recommend the book highly enough, I use it in my compilers class.
