We use C++ and care about real time performance, but also use this JSON library, the thing is that we use JSON for loading and configuring data which happens during load time which is infrequent and don’t need JSON during the critical update path. Previously we used rapid json which is faster but the syntax of the nlohmann json is nicer and it is much quicker to develop with.. we also use python a lot so the familiarity between the 2 is also useful, some of the other C++ json libs can have quite convoluted api’s for dealing with values, objects and arrays.
