Can we are using Cordova and Capacitor in same project?

I am building project with Ionic 5.

Yes you can. I’m doing this myself. It is done though capacitor

https://capacitor.ionicframework.com/docs/cordova/using-cordova-plugins/

I can think of two ways to interpret this question, to which I would have two different answers:

A: can capacitor also bridge to cordova plugins? a qualified “yes” here, as @Vigors says. some cordova plugins are compatible, but not all.

B: can I build with both cordova and capacitor? I can’t think of a benefit to trying to do this.
