使用Map

const data = {
  Languages: [
    {
      PKM: 'Languages',
      Title: 'Tamil2',
    },
    {
      PKM: 'Languages',
      Title: 'தமிழ்',
    },
    {
      PKM: 'Languages',
      Title: 'English',
    },
  ],
  status: 'success',
  message: 'Retrieve Success!',
};

渲染时

{data.Languages.map((item) => (
  <Text>{item.Title}</Text>
))}

更新码

import React, { useEffect, useState } from 'react';
import { Text, View, StyleSheet, FlatList } from 'react-native';
import Constants from 'expo-constants';

const data = {
  Languages: [
    {
      PKM: 'Languages',
      Title: 'Tamil2',
    },
    {
      PKM: 'Languages',
      Title: 'தமிழ்',
    },
    {
      PKM: 'Languages',
      Title: 'English',
    },
  ],
  status: 'success',
  message: 'Retrieve Success!',
};

export default function App() {
  // const [data, setData] = useState([]);

  // useEffect(() => {
  //   fetch('https://dummyjson.com/products/1')
  //     .then((res) => res.json())
  //     .then((json) => {
