Multi-Paradigm Programming with Modern C++ - Using Lambdas

The video tutorial explains the use of lambdas as callback functions, highlighting their role in event-driven programming. It introduces STD function as a universal abstraction for function objects, emphasizing its advantages over traditional function pointers. The tutorial discusses reducing code coupling through callbacks and dependency injection, using a logger class as an example. Practical implementation of callbacks in a server context is demonstrated, focusing on error handling and logging. The video concludes with a discussion on maintaining small callback functions and avoiding dependency magnets.
