Komponen Inti React Native vs DOM Web

Mengapa Tidak Ada HTML di React Native?

Tampilan — Padanan div

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

function Card() {
  return (
    <View style={styles.card}>
      {/* children go here */}
    </View>
  );
}

const styles = StyleSheet.create({ card: { padding: 16, borderRadius: 8 } });

Teks — Padanan p/span

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

function Greeting() {
  return (
    <View>
      <Text style={{ fontSize: 24, fontWeight: 'bold' }}>Hello!</Text>
      <Text>Welcome to React Native.</Text>
    </View>
  );
}

Gambar — Padanan img

import { Image } from 'react-native';

// Local asset:
<Image source={require('./assets/logo.png')} style={{ width: 100, height: 100 }} />

// Network image (must provide dimensions):
<Image source={{ uri: 'https://example.com/photo.jpg' }} style={{ width: 200, height: 150 }} />

ScrollView — Padanan overflow:scroll

import { ScrollView, Text } from 'react-native';

function Article({ paragraphs }) {
  return (
    <ScrollView>
      {paragraphs.map((p, i) => <Text key={i}>{p}</Text>)}
    </ScrollView>
  );
}

FlatList — Daftar Tervirtualisasi

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

function UserList({ users }) {
  return (
    <FlatList
      data={users}
      keyExtractor={u => u.id}
      renderItem={({ item }) => <Text>{item.name}</Text>}
    />
  );
}

  );
}

  );
}
