React Native Web

There's a little comparison between like Tomagui and React Native Web and Ndripsy and Native base which is quite a lot slower. What are the primary things going on under the hood that make it so much more performant than the alternatives? I've definitely been pressing on the performance side but we had a long standing relationship with the database they're great people over there okay cool yeah no I always feel like you know you want to build your own UI kit or an app in this way.
