Learning React Native as a beginner is an exciting journey, and choosing between React Native CLI and React Native Expo is an important decision. Here's a brief overview of both options to help you make an informed choice:

React Native CLI (Command Line Interface):

Pros:

1. Flexibility: React Native CLI provides more flexibility in project configuration. You have direct access to native modules and can modify the native code as needed.

2. Native Modules: If your project requires native modules or dependencies that are not supported by Expo, using React Native CLI is a better choice.

3. Full Control: With React Native CLI, you have full control over the build process and can customize it according to your project's requirements.

Cons:

1. Learning Curve: React Native CLI has a steeper learning curve for beginners, as it involves more manual configuration and understanding of native development concepts.

2. Setup Complexity: Setting up a new project with React Native CLI can be more complex compared to Expo.

React Native Expo:

Pros:

1. Quick Setup: Expo offers a quick and easy setup for new projects. You can get started with a new app without the need for Android Studio or Xcode.

2. Over-the-Air (OTA) Updates: Expo supports over-the-air updates, allowing you to push updates to your app without requiring users to download a new version from the app store.

3. Simplified Development: Expo abstracts away much of the native development complexity, making it easier for beginners to focus on building features without worrying about native code.

Cons:

1. Limited Native Modules: Expo restricts direct access to certain native modules. If your project requires custom native modules or third-party libraries not supported by Expo, you might face limitations.

2. Less Control: You have less control over the native build process. If you need to make significant changes to native code, Expo might not be the best fit.

Recommendation:

• Start with CLI For beginners, especially those who are new to mobile development, CLI is a great starting point. It is little bit diffculty on environment development setup. When I was start the react native using expo after some time I realize CLI is use as professionally then my mind is divert towards CLI that why you should focus on react native CLI on the starting point which give you good experience, allows you to quickly prototype, and is well-suited for a wide range of applications.

• Condition: If you face difficulty while understand the React Native CLI then definitely use React Native Expo.

• Transition to CLI if Needed: As you gain more experience and encounter specific requirements that Expo cannot fulfill, you can consider transitioning to React Native CLI for more control and customization.

Whichever option you choose, there is a wealth of online resources, tutorials, and a supportive community to assist you in your React Native journey.
