create a react native app with expo without using typescript

React Native, combined with Expo, provides an easy and efficient way to build mobile applications. While TypeScript is commonly used for type safety, many developers prefer JavaScript for its simplicity and faster setup.

Prerequisites

Before getting started, ensure you have the following installed:

• Node.js 

• npm or yarn ( you will get it along node js)

• Expo CLI (for building app for production )

Setting Up the Expo App

The original setup that expo@latest would give you includes file-based routing. To create a new React Native project without TypeScript, run the following command:

npx create-expo-app your-appname --template blank

you can replace your-appname with name of your choice

additionally you need to install some other packages such as expo router

npx expo install expo-router

Once the project is created, navigate to your project directory:

cd your-appname

Project Structure

Your project structure should look like this:

your-appname/ ├── App/ ├── package.json ├── node_modules/ ├── assets/ ├── babel.config.js └── app.json

How to use expo routing

create _layout.js in app folder as

import React from "react";

import { Stack } from "expo-router";
export default function RootLayout() {
return (
<Stack screenOptions={{ headerShown: false }} />
);
}
here context api or redux can be used by wrapping Stack.
Conclusion
By following these steps, you have successfully set up a React Native Expo app
without TypeScript. You can now build and expand your app using JavaScript, 
React Navigation, and styling libraries like NativeWind.
