Hard
Consider the following code:
import React from 'react'
import { View, Text, FlatList } from 'react-native'
const titles = [
{ title: 'title 1', key: 'i1' },
{ title: 'title 2', key: 'i2' },
...
]
const _keyExtractor = (item, index) => item.key
const ListComponent1 = () => (
<View>
{titles.map(item => <Text key={item.key}>{item.title})}
</View>
)
const ListComponent2 = () => (
<FlatList
data={titles}
keyExtractor={_keyExtractor}
renderItem={({item}) => <Text title={item.title} />}
/>
)
What are the true statements?
