This is not a problem specific to backbone rendering. This is a common issue in jQuery plugins, and vanilla javascript in general. Its a best practice overall to keep your functions small. Have them do one thing and do it well, keep them unix like, small sharp tools. You can always copy paste a large conditional from one function into its own named function. This significantly improves readability and divides the code in to smaller units which makes testing more graceful.
