If you're writing a Rails app, you may reach for
String#constantize(provided by Active Support Core Extensions) when you have a variable that may resolve to a class name and your control flow is to execute that classes code in some manner.This benchmarks using
String#constantizevs a simple comparison, showing the latter is much faster.
