Luckily there are many Parsing Libraries in the JavaScript eco-system, So we won't have to find out if this convoluted approach is worthwhile :)

BNF sounds like the standard approach. Are there any BNF parsers + generators usable from Javascript?

PEG is another popular approach

jison works fairly well, and is mostly compatible with bison.

Some of the top of my Head:

  - Antlr (https://github.com/antlr/antlr4/blob/master/doc/javascript-target.md)

  - PegJS (https://github.com/pegjs/pegjs)
