Exploring the latest trends in React Native

• React Native CLI and Expo: Developers have the choice between using React Native CLI or Expo for project setup and management. Expo offers a suite of tools and services crafted to make React Native development faster and easier, especially for beginners. However, React Native CLI provides more flexibility and access to native modules.
• TypeScript Integration: TypeScript adoption in React Native projects is growing steadily. TypeScript adds static typing to JavaScript, which helps catch errors early and improves code quality, making it a preferred choice for large-scale applications.
• Functional Components and Hooks: With the introduction of React Hooks, functional components have become the preferred way of building React Native applications. Hooks like useState, useEffect, useContext, etc. simplify state management and side-effects handling, leading to cleaner and more modular code.
• State Management with Context API and Redux Toolkit: The context API, along with the Reducer hook, is often used to manage local states within components. For more complex state management needs, the Redux Toolkit offers a simplified way to set up Redux with React, providing utilities like createSlice for reducers.
