What is the best way to make a mobile application - in Java or JavaScript (ReactNative)?

Question

Java

I don't know much about coding (I work as a designer), but sometimes there is a desire to code something.
A couple of years ago I studied C# a little, now I have JavaScript + React for a couple of months.
Now I want to try to make a mobile application, first for Android, then preferably without a radical rewrite - on ios.
Actually, what is better to learn Java from scratch (it seems to be more native, but it’s not clear how to redo it later for ios, and the motivation may disappear - again from scratch to learn all the basics), or React Native (as I understand it, there will be fewer edits)?
ps I'm unlikely to work as an encoder, it's more for myself.

Answer 1

for a beginner, especially those familiar with javascript, reactive will be easier.
but you need to look at things soberly: any react native and the like will smoke on the sidelines compared to native. especially if more than just banality is required.

Answer 2

Under your conditions, there is only one option - React Native.

Answer 3

The answer depends on asking the right questions. In general, yes, native, Java/Kotlin is better.
But you want cross-platform and for small tasks for yourself, then yes, you can ReactNative or Ionic. Look also in the direction of Flutter, it is now being actively promoted by Google as a replacement for the same ReactNative.

Answer 4

потом желательно без радикального переписывания - на ios.

React Native
If you need native support for android, then definitely Java || Kotlin.
