awesome-json-next VS json5

You might look at JSON Next variants (if you remember - "classic" JSON is a subset of YAML), see https://github.com/json-next/awesome-json-next

my own little JSON Next entry / format is called JSON 1.1 or JSONX, that is, JSON with eXtensions, see https://json-next.github.io/

FYI: I collect JSON variants with extension at the Awesome JSON - What's Next? page [1].

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.
