How to use React Native code, which is available as a string, in my application?

I have some react native code available in a string variable:

let customCode='<View><Text style={{fontSize:20}}>Hello World!</Text></View>'

How can I use this in my react native application and display the ‘View’ to the user.

Here’s my code –

import React from 'react';
import { View, Text, StyleSheet } from 'react-native';

export default const SimpleComponent = () => {
  let customCode='<View><Text style={{fontSize:20}}>Hello World!</Text></View>'

  return (
    <View style={styles.container}>
      <Text style={styles.text}>Hello World</Text>
      <View>{customCode}</View>
    </View>
  );
};

I used the customCode variable in my return part like this

return (
    <View style={styles.container}>
      <Text style={styles.text}>How are you</Text>
      <View>{customCode}</View>
    </View>
  );

but it just treats the customCode variable as a string instead of actual react native code.
