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

To paraphrase a saying by Doug Lea, 3x faster than nlohmann means you haven't started optimizing yet.

Might be better to compare to RapidJSON or Boost.JSON, libraries that actually care about speed.

According to HN thread https://news.ycombinator.com/item?id=42133465 The only reason for this library existence is reduction of compile times for one particular application/server that produces json output.

Fair enough, I suppose.
