sexp VS json5

There's a tool sexp that Jane Street uses internally to slice and dice sexp logs, but, yes, I get that there aren't logging services out there that support sexps. They should, though, as sexps have unique advantages over JSON. They tend to be more human-readable too. Great blog post overall!

JSON5 support

Meanwhile, formats have been evolving (JSON5, YAML), config entry points are constantly changing. These fluctuations, fortunately, were covered by tools like the cosmiconfig.

I think JSON5 is fairly close to this: https://json5.org

I reckon the only thing it's missing to be truly accessible to non-techies is that string values still need to be quoted, i.e. you can't have:

key: this is my value

(I'm definitely not saying it would be a good idea to allow quotes to be dropped, just that that's the only potential stumbling block I see for non-techies.)

I believe that's JSON5.

It's my preferred configuration file format, it fixes all the problems I have with JSON (trailing commas, comments) without turning it into a mess full of gotchas like YAML.

JSON 5 support

I would like to see mention of JSON5 which is 11 years its elder. For comments in JSON, JSON5 is a good starting point.
