Summary
This episode explores C++17's newly approved 'constexpr if' feature, which allows for compile-time conditional branching. Jason demonstrates how the feature works by creating template functions that behave differently based on compile-time type traits. He shows how code blocks inside constexpr if statements are only compiled if the condition is true, improving efficiency and enabling cleaner template metaprogramming. Jason also explains the limitations of compound conditions and how to structure code properly for complex compile-time conditionals.
