How can I organize data from A to Z in alphabetical order in React Native when the user chooses the A to Z option from the dropdown menu?

Question

How can I organize data from A to Z in alphabetical order in React Native when the user chooses the A to Z option from the dropdown menu?

I am working on a screen that can display up to 1000 data retrieved from the API.

Here is the image:

Now, I have implemented a drop-down box where users can select alphabetically from A to Z. After selecting an alphabetical order, the data will be arranged accordingly. How can I achieve this functionality in my code?

I have tried the following code snippet:

// setData(json.results);  <==================it for sorting
      // setData((prevData) => [...prevData, ...newData]);

      // const sorted = [...sortedData, ...newData].sort((a, b) => {
      //   const lastNameA = a.name.first.toLowerCase();
      //   const lastNameB = b.name.first.toLowerCase();
      //   if (lastNameA < lastNameB) return -1;
      //   if (lastNameA > lastNameB) return 1;
      //   return 0;
      // });
      // setSortedData(sorted);

However, it is not functioning as expected when I select the A to Z list in the drop-down box.

Can someone guide me on how to achieve this successfully?

Code:

import {
  StyleSheet,
  Text,
  View,
  Image,
  TextInput,
  FlatList,
  ActivityIndicator,
  SafeAreaView,
} from 'react-native';
import React, { useEffect, useState } from 'react';
import { scale, verticalScale, moderateScale } from 'react-native-size-matters';
import { RFPercentage } from 'react-native-responsive-fontsize';
import SelectDropdown from 'react-native-select-dropdown';

const sortby = ['A to Z', 'Newest', 'Oldest'];

const App = () => {
  // rest of the code...
};

export default App;

// rest of the styles and components...

Here's a code snippet that has worked well for me:

import {
    StyleSheet,
    Text,
    View,
    Image,
    TextInput,
    FlatList,
    ActivityIndicator,
    SafeAreaView,
} from 'react-native';
import React, { useEffect, useState } from 'react';
import { scaleSizes, responsiveFontSizes } from 'react-native-size-matters';
import SelectDropdown from 'react-native-select-dropdown';

const sortingOptions = ['A to Z', 'Newest', 'Oldest'];

const App = () => {
    const [loading, setLoading] = useState(true);
    const [data, setData] = useState([]);
    const [search, setSearch] = useState('');
    const [filteredData, setFilteredData] = useState([]);
    const [masterData, setMasterData] = useState([]);
    const [totalItems, setTotalItems] = useState(0);
    const [searchResultsCount, setSearchResultsCount] = useState(0);

    useEffect(() => {
        fetchData();
    }, []);

    const fetchData = async () => {
        try {
            const response = await fetch('https://randomuser.me/api?results=1000');
            const json = await response.json();
            
            setLoading(false);
            setFilteredData(json.results);
            setMasterData(json.results);
            setTotalItems(json.info.results);
        } catch (error) {
            console.error(error);
        }
    };

    const searchFilterFunction = (text) => {
        if (text) {
            const updatedData = masterData.filter((item) => {
                const itemData = item.name.first ? item.name.first.toUpperCase() : '';
                const searchText = text.toUpperCase();
                return itemData.includes(searchText);
            });
            setFilteredData(updatedData);
            setSearch(text);
            setSearchResultsCount(updatedData.length);
        } else {
            setFilteredData(masterData);
            setSearch(text);
        }
    };

    const renderItem = ({ item }) => (
        <View style={{ padding: 10 }}>
            <Text>Name: {`${item.name.first} ${item.name.last}`}</Text>
            <Text>Email: {item.email}</Text>
            <Text>City: {item.location.city}</Text>
            <Text>State: {item.location.state}</Text>
            <Text>Country: {item.location.country}</Text>
            <Text>Postcode: {item.location.postcode}</Text>
        </View>
    );

    const ItemSeparatorView = () => (
        <View
            style={{
                height: 0.5,
                width: '100%',
                backgroundColor: '#000',
            }}
        />
    );

    return (
        <View>
            {/* UI components and functionality */}
        </View>
    );
};

export default App;

const styles = StyleSheet.create({
    container: {
        flex: 1,
    },
    // styles for different UI elements like header, input fields, buttons, etc.
});

Make sure to handle all other available options as well! 😉
