Complete Modern C++ - Using std::promise

The video tutorial explains the concepts of promise and future in programming, focusing on how they enable asynchronous communication between threads. A promise is used to store a value or an exception, which can be accessed later by a future object in another thread. The tutorial highlights that promise and future operations are thread-safe and synchronized. An example is provided to demonstrate how a promise can be used to pass data between threads, with the main thread notifying a task operation when the data is ready. The tutorial concludes by emphasizing the use of promise and future for data sharing without manual thread synchronization.
