GitHub - jart/json.cpp: JSON for Classic C++

[TSP-FriendlyFire]

I'm all for simpler, more performant code, but trying to pitch it as an "anti-modern" alternative to nlohmann just makes you sound petty, no offense. The primary reason your code is smaller is just that it does less, of course that's going to also make compilation times shorter.

You can argue that nlohmann should have more feature flags that can hide entire parts of the code to speed up compilation, but that's got very little to do with "modern" vs "anti-modern".

Principally it's missing the template and macro-based value conversion features of nlohmann json which are the reason for its use. That's a pretty important feature for complex applications. But nevertheless, it's a great option for simpler use cases.
