I have done the same thing! Read Crafting Interpreters but wrote the first half in Clojure instead of Java.

I think it's a good method for experienced programmers, who are self-taught (like me) or just want to brush up some skills and knowledge.

Yes, you stay engaged, but there is also something to be said about porting code between different languages. The differences, strengths, weaknesses etc. stand out more, similarities become more clear and things that seem different, but are analogous emerge.
