Serializing? For serializing you probably want performance above all else. I’m saying this without checking any benchmark, but I’m sure yaml is more expensive to parse than other formats where indentation don’t have meaning.
For human readability: it has to be readable (and writeable) by all humans. I know (a lot of people) that dislike yaml, toml and XML. I don’t know of a single person that struggles to read/write json, there is a clear winner.
JSON would be perfect if it allowed for comments. But it doesn’t and that alone is enough for me to prefer YAML over JSON. Yes, JSON is understandable without any learning curve, but having a learning curve is not always bad. YAML provides a major benefit that is worth the learning curve and doesn’t have the issues that XML has (which is that there is no way to understand an XML without also having the XSD for it)
If a comment isn’t part of the semantic content of a JSON object it has no business being there. JSON models data, it’s not markup language for writing config files.
For the data interchange format, comments aren’t part of the JSON grammar but the option to parse non-JSON values is left open to the implementation. Many implementations do detect (and ignore) comments indicated by e.g. # or //.
Serializing isn’t necessarily about performance, or we’d just use protobuf or similar. I agree Json is a great all rounder. Combine with JSON object schema to define sophisticated DSLs that are still readable, plain JSON. TOML is nice as a configuration language, but its main appeal (readability) suffers when applied to complex modeling tasks. XML is quite verbose and maybe takes the “custom DSL” idea a little too far. YAML is a mistake.
I don’t know why we’re fucking about trying to use text editors to manipulate structured data.
Yeah, it’s convenient to just be able to use a basic text editor, but we’re not trying to cram it all on a floppy disk here. I’m sure we could have a nice structured data editor somewhere for all those XML, JSON and YAML files we’re supposed to maintain every day.

Json should also allow for trailing commas. There’s no reason for it not too. It’s annoying having to maintain commas.
And also a standard date time type!
What is wrong with ISO 6801 strings?
11-2023-14
I dunno it just kinda looks weird to me
Dunno what format you’ve got there, but ISO 6801 looks like

You can use comments in JSON schema (in a standardized way) when they are semantically relevant: https://json-schema.org/understanding-json-schema/reference/comments
For the data interchange format, comments aren’t part of the JSON grammar but the option to parse non-JSON values is left open to the implementation. Many implementations do detect (and ignore) comments indicated by e.g. # or //.
JavaScript package management promptly said otherwise. JSON is a config format no matter if you like it or not.
Really? Any JSON over 80 chars becomes a nightmare to read for me, especially if indention is not used to make it more readable.
