If you have a constant expression like 1 + 2 in your code you can evaluate it at compile time once and avoid computing it at runtime. You can do that with control flow and much more complex language constructs in C++. If you want to know more about that look into C++ template meta programming, constexpr, and constval.
That was the point 20 years ago. These days it is pivoting to compile time functional programming
What does that mean ?

Templates are cool as fuck tho… For like 5 minutes until you go insane
I get that the designers wanted to have compile time static replacement but this was not the way to do it.
