Complete Modern C++ - Variadic Templates - Part II (C++11)

The video tutorial covers the use of recursion with variadic templates, focusing on how to stop recursion using a base case function. It demonstrates printing arguments with a separator and addresses the issue of extra commas. The sizeof operator is introduced to manage function parameter packs. The tutorial also discusses passing arguments by constant reference to optimize performance and introduces perfect forwarding using rvalue references, explaining reference collapsing rules.
