如何在react native中将以前的文本与新的文本连接起来

import React from 'react';
import { Text } from 'react-native';

class MyComponent extends React.Component {
  render() {
    const previousText = "Hello";
    const newText = "World";
    const combinedText = previousText + " " + newText;

    return (
      <Text>{combinedText}</Text>
    );
  }
}
