What does HackerNews think of folly?

An open-source C++ library developed and used at Facebook.

Language: C++

Not sure if it's still the case but about 6 years ago Facebook's folly C++ library was something I'd point to for my junior engineers to get a sense of "good" C++ https://github.com/facebook/folly
Ideally they should be turned into open source projects.

Google's https://abseil.io and Facebook's https://github.com/facebook/folly come to mind.

Any specific examples come to mind? I usually find Folly [1], Abseil [2] or the EASTL [3] beat the standard library on almost every metric you can imagine, including the under appreciated compile time metric.

And then of course there's boost [4], but people have very mixed opinions about it.

The reason a lot of developers use the standard library in C++ is because dependency management in C++ such a nightmare that many people writing a library are forced to use the standard if they want any hope of adoption even when far superior options exist. It's literally something people writing C++ libraries will advertise "Dependency free header only library!" because they know without that a lot of developers won't bother using it.

Anyways, I would be interested to know what part of the standard library you find is better than third party options.
