How to capitalize first letter of text in React Native?

To capitalize first letter of text in React Native, we can create our own function.

For instance, we write:

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

const capitalize = (str) => {
  return str[0].toUpperCase() + str.slice(1);
};

export default function App() {
  return (
    <View>
      <Text>{capitalize('hello')}</Text>
    </View>
