In your example it the answer may be “none”, but I’d be curious of the amount of tech debt that may have been introduced by the jr vs the sr’s; whether or not sr’s had better intuition.

Jr introduced far less tech debt because they knew the patterns and best practices around the tech stack where as the Sr developers didn't.

So the Sr devs wrote a bunch of really funky react code and the jr dev just wrote normal looking react code.
