This is a new React Native project, bootstrapped using @react-native-community/cli.

Getting Started

Note: Make sure you have completed the React Native - Environment Setup instructions till "Creating a new application" step, before proceeding.

Step 1: Start the Metro Server

First, you will need to start Metro, the JavaScript bundler that ships with React Native.

To start Metro, run the following command from the root of your React Native project:

# using npm
npm start

# OR using Yarn
yarn start

Step 2: Start your Application

Let Metro Bundler run in its own terminal. Open a new terminal from the root of your React Native project. Run the following command to start your Android or iOS app:

For Android

# using npm
npm run android

# OR using Yarn
yarn android

For iOS

# using npm
npm run ios

# OR using Yarn
yarn ios

If everything is set up correctly, you should see your new app running in your Android Emulator or iOS Simulator shortly provided you have set up your emulator/simulator correctly.

This is one way to run your app — you can also run it directly from within Android Studio and Xcode respectively.

Step 3: Modifying your App

Now that you have successfully run the app, let's modify it.

1. Open App.tsx in your text editor of choice and edit some lines.

2. For Android: Press the R key twice or select "Reload" from the Developer Menu (Ctrl + M (on Window and Linux) or Cmd ⌘ + M (on macOS)) to see your changes!

   For iOS: Hit Cmd ⌘ + R in your iOS Simulator to reload the app and see your changes!

Congratulations! 🎉

You've successfully run and modified your React Native App. 🥳

Difference between Test and it in writing test cases

It is an alias for tests, so they are functionally the same.

So, what makes it different?

This alias is created to make your tests more readable from a test output point of view.

It can help make your tests more readable from a readability point of view.

What design pattern does follow React ?

React doesn't follow just one specific design pattern, but rather leverages several different patterns to achieve its functionality and promote good development practices. Here are some of the key design patterns used in React:

Component-based Architecture: This is the core principle of React, where complex UIs are built by composing smaller, reusable components. It promotes modularity, maintainability, and code reuse.

Declarative Programming: React components describe what the UI should look like, and React handles the updates efficiently when data changes. This leads to cleaner and more predictable code.

Virtual DOM: React creates an in-memory representation of the real DOM and only updates the actual DOM when necessary. This significantly improves performance and reduces unnecessary re-renders.

Other commonly used patterns:

Presentational vs. Container Components: This pattern separates presentational concerns (how the UI looks) from container concerns (data fetching and logic).
Higher-Order Components (HOCs): These are functions that take a component and return a new component with additional functionality. They are useful for code reuse and abstraction.
Render Props: This pattern allows passing rendering logic as props to child components, providing flexibility and customization.
Hooks: Introduced in React 16.8, hooks allow using state and other React features in functional components without relying on class components.
These are just some of the most common design patterns used in React. The choice of which pattern to use depends on the specific situation and developer preferences. Remember, the ultimate goal is to write clean, maintainable, and performant code.
