Is React Native alternative to Java and Kotlin native apps?

Question

Building native apps is harder in Java, so what is better React Native (think JS) or Java and Kotlin. Performance: is React Native apps are performant as Java and Kotlin, I ask because hybrid mobile apps are not performant and how about React Native

Answer 1

Absolutely.
It's even much simpler. In addition, with react native, your code also allows you to target iOS.

It is also almost identical to react js.
As a result, web + native Android/iOS with very little code.

Performance level is very good, because after that, it translates into native code.

I mean, it's Facebook behind so serious.

Answer 2

Yep, they are quite similar in terms of performances, you can replace Java and Kotlin w/h RN and AFAIK you can also get a discrete control of your device by using external modules.

Of course, if you already know JS, it worth a try, otherwise... don't give up and try to learn Java, Sololearn offers an excellent course to get started.
