I believe that 99% of the time, a reuse of older technologies results in greater innovation that is more stable and a return is multiple of the underlying foundations. This applies here as well. Typescript could go a long way. But admittedly, writing a grammar, parser and then a whole compiler along with its tooling of a new DSL is fun for sure but does look good on CV as well. I didn't say anything more than that.
