Absolutely agree, I avoid react / JavaScript ‘apps’ at all cost, they perform poorly, use excessive resources and seem to discourage an engineering mindset when writing code.
The Trips tab in the app (itinerary) was actually rewritten in native after originally being implemented using RN.
It’s really too bad that people have this perception of RN’s use at Airbnb. I feel like people assume the whole thing is RN, which couldn’t be more wrong.
