Anna wants to speed up her code which has a small function that gets called multiple times within a loop. What could she consider making that function?

Anna should consider making the function inline. Inlining a function means that instead of calling the function, the compiler will insert the function's code directly at the call site. This can eliminate the overhead of function calls and improve performance, especially when the function is small and called frequently in a loop. However, inlining should be used judiciously as it can lead to code bloat if overused.
