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#constantize vs a simple comparison, showing the latter is much faster.

Sorry, something went wrong.

Uh oh!
