Perfect Forwarding

When we talk about Perfect Forwarding, we're diving into one of the more powerful features added to C++11. Have you ever found yourself in a situation where passing arguments through multiple layers of functions led to unnecessary copies or even worse, performance pitfalls?

If so, you’re not alone. Perfect Forwarding allows you to pass arguments to functions while preserving their value category, meaning you can avoid these costly mistakes.

In this chapter, we will unpack what Perfect Forwarding is, how it works with templates, and why it’s a must-know concept for modern C++ developers.
