Worth noting that JSC on iOS for use in app-backend/business-logic code runs in interpreted mode [1].
Are Android versions of RN apps faster because Android's native V8 allows JIT, and Hermes also employs JIT?

- saghul 7y agoRN on Android also uses JSC, so no JIT. And, and per the video (https://www.youtube.com/watch?v=zEjqDWqeDdg&feature=youtu.be&t=130 https://www.youtube.com/watch?v=zEjqDWqeDdg&feature=youtu.be...) there is no JIT on Hermes either.
