How to get into React Native?

To get started with React Native, you should first have a solid understanding of React and JavaScript. Here are the basic steps to getting started with React Native:

  1. Install the React Native CLI (Command Line Interface) by running npm install -g react-native-cli

  2. Create a new project by running react-native init MyProject

  3. Run the project on an emulator or device by running react-native run-ios or react-native run-android

  4. Begin developing your app by editing the files in the src directory of your project

  5. Use React Native's built-in components, such as View, Text, and Image, to build your user interface

  6. Utilize React Native's APIs, such as Fetch and AsyncStorage, to access device functionality and data

A simple Calculator Program:

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

const Calculator = () => {
    const [input, setInput] = useState('');
    const [result, setResult] = useState('');

    const handleButtonPress = (val) => {
        setInput(input + val);

    const handleClearPress = () => {

    const handleEqualPress = () => {

    return (
                <Button title="1" onPress={() => handleButtonPress(1)} />
                <Button title="2" onPress={() => handleButtonPress(2)} />
                <Button title="3" onPress={() => handleButtonPress(3)} />
                <Button title="+" onPress={() => handleButtonPress('+')} />
                <Button title="4" onPress={() => handleButtonPress(4)} />
                <Button title="5" onPress={() => handleButtonPress(5)} />
                <Button title="6" onPress={() => handleButtonPress(6)} />
                <Button title="-" onPress={() => handleButtonPress('-')} />
                <Button title="7" onPress={() => handleButtonPress(7)} />
                <Button title="8" onPress={() => handleButtonPress(8)} />
                <Button title="9" onPress={() => handleButtonPress(9)} />
                <Button title="*" onPress={() => handleButtonPress('*')} />
                <Button title="." onPress={() => handleButtonPress('.')} />
                <Button title="0" onPress={() => handleButtonPress(0)} />
                <Button title="C" onPress={handleClearPress} />
                <Button title="/" onPress={() => handleButtonPress('/')} />
                <Button title="=" onPress={handleEqualPress} />

export default Calculator;

You could show how it looks in the UI of the mobile app on iOS, for example, but aside from that, I like the way you made it very simple ๐Ÿ™‚

One thing I would have added would be a comparison between the same code snippet in React.

Great article in general!๐Ÿ‘
