Which is why many parsers support that. I'm positive you'll find one that does so in pretty much every environment.

In that case, you might want to have a look at JSON5: https://json5.org/

It is pretty niche, but attempts to improve upon JSON in a multitude of ways, one of which is the support for comments: https://spec.json5.org/#comments

The libconfig format is fairly close to that, and it's great!
