Answer 1

No, all programming language have different purpose but if you want to make an app
For android -> kotlin (primary language and easy) java(secondary)
For iOS -> swift/objective c
For both -> flutter(has high community support and best ui) needs dart language skill, react native needs js skill, ionic needs js skill, kivy(low community support and low ui) needs python skill
