Question

_onPress(e) {
         


        

Answer 1

The concern is about performance so I solve it with this approach

just create a wrapper around TouchableOpacity or any clickable view

import { TouchableOpacity } from "react-native"

export const TouchableOpacityOnPressOptimized = ({ children, onPress, index }) => {
  return (
     onPress(index)}>
      {children}
    
  )
}

const touchMe = (index) => {
    switch(index) {
       case 1: alert('index is' + index)
       case 2: alert('index is' + index)
    }
}

 touch me 1 

 touch me 2 

 touch me 3 

this way your touchable component not re-render
