Need a comparison with other C JSON libraries

[eyalroz]

There are several C libraries for JSON parsing which are relatively or very popular, even here on GitHub (e.g. json-c, cJSON, janson). It would help if you could post a comparison of the foci, strengths and weaknesses of these other libraries vis-a-vis oj. It could be a Wiki page or a README section.

Now, it's true that the best comparison would be some third-party surveying multiple libraries impartially, but - it is also meaningful to read library authors' explanations of why they "rolled their own" rather than using an existing library; and what they see as the main differences.

There is a comparison with simdjson here. What do you think about just expanding that to include other libraries?

Also, note the fun race comparison: https://github.com/ohler55/ojc/blob/master/misc/compete.md

What do you think about just expanding that to include other libraries?

Well simdjson is C++, but that's certainly useful. Now, what I see in that comparison are supported features and performance figures; it would be great to have this for other C-language JSON libraries. However, when the language is the same, it's also useful to compare the API. Still, whatever you feel like writing would help.

APIs are somewhat subjective in so it's tough to rate them but with the benchmarks in place there will be coding examples of the API use.

It's not about rating, it's just "here's how you do X with oj, and here's how you do it with this other library".

Ok, I think benchmark code would demonstrate use. I'll make this a lower priority task for now though.
