The document discusses effective study of modern C++. It covers topics like constexpr for defining constants, futures and promises for asynchronous programming, shared futures for sharing future states between objects, and packaged tasks for launching functions asynchronously using threads. Examples are provided for defining constants with constexpr, getting futures from promises, storing futures in vectors and classes, and using packaged tasks to launch tasks on threads.
