How do I render different JSX depending on the platform the user is running?

import React, { Component } from "react";
import PropTypes from "prop-types";
import { StyleSheet, TouchableOpacity, TouchableHighlight, Platform, Text, Image } from "react-native";

export default class RoundButton extends Component {
    constructor(props) {
        super(props);
    }

    render() {
      const JSX = Platform.OS === "ios" ? <TouchableOpacity> : <TouchableHighlight>

        return (
            <JSX style={styles.container}>
                <Text style={styles.buttonText}>{this.props.title}</Text>
            </JSX>
        );
    }
}

Your code posted in question will also work with just minor change. Just remove those tags and use component name while performing the conditional operation.

import React, { Component } from 'react';
import PropTypes from 'prop-types';
import {
  StyleSheet,
  TouchableOpacity,
  TouchableHighlight,
  Platform,
  Text,
  Image,
} from 'react-native';

export default class RoundButton extends Component {
  constructor(props) {
    super(props);
  }

  render() {
    const JSX = Platform.OS === 'ios' ? TouchableOpacity : TouchableHighlight; // remove those tags and use simple Component name.

    return (
      <JSX onPress={() => alert('Hi')} style={styles.container}>
        <Text style={styles.buttonText}>{'Hi'}</Text>
      </JSX>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop: 20,
  },
  buttonText: {},
});

7 Ways to Implement Conditional Rendering in React Applications , To do this we use a set of curly braces {} and write our JavaScript within. The caveat however is that there is a limit to what can be done within  Conditional Rendering. In React, you can create distinct components that encapsulate behavior you need. Then, you can render only some of them, depending on the state of your application. Conditional rendering in React works the same way conditions work in JavaScript.

simply do this:

render(){
     if(Platform.OS === "ios"){
          return (
            <TouchableOpacity style={styles.container}>
                <Text style={styles.buttonText}>{this.props.title}</Text>
            </TouchableOpacity >
          );
      else{
          return (
            <TouchableHighlight style={styles.container}>
                <Text style={styles.buttonText}>{this.props.title}</Text>
            </TouchableHighlight >
          );
      }
}

or this one:

   render(){

        const JSX = Platform.OS === "ios" ? <TouchableOpacity style={styles.container}><Text style={styles.buttonText}>{this.props.title}</Text></TouchableOpacity > : <TouchableHighlight style={styles.container}><Text style={styles.buttonText}>{this.props.title}</Text></TouchableHighlight >

        return (JSX);

    }

The result

simply you can use Ternary operators

render(){ return( <View> { Platform.OS === "ios" ? <TouchableOpacity style={styles.container}> <Text style={styles.buttonText}>{this.props.title}</Text> </TouchableOpacity > : <TouchableHighlight style={styles.container}> <Text style={styles.buttonText}>{this.props.title}</Text> </TouchableHighlight > } </View> ) }
