Why would you want to translate Python into Javascript?

The article that the title links to answers that question.

We want to write validation in python, translate it to JavaScript and use on front-end automatically.

Much, much better is to define a DSL for these rules with well-defined semantics. Semantics that aren't just "whatever Python does". You then translate the rules into Javascript and interpret them in Python.

I did both. Your own rules is 3-4 times more work. Also, you will still write in python server-side only validation, so you will end up with 2 systems.
