400+ React Native Interview Questions Practice Test

🎉 Welcome to the React Native Mastery Course!

You've just reviewed some key concepts that are crucial for anyone looking to become proficient in React Native. Whether you're preparing for an interview or simply looking to deepen your understanding of React Native, these topics are fundamental to your journey.

Here's a quick recap of what we've covered:

1. Understanding JSX and Its Role: JSX is a syntax extension for JavaScript that allows you to write HTML elements in JavaScript instead of using string concatenation or other methods. It plays a crucial role in the development process by providing a clear structure that maps directly to the rendered components.

2. Component Lifecycle: Components in React Native have lifecycle methods that enable you to run code at specific times during the component's process from birth (creation) to death (removal from the DOM). Understanding these lifecycle hooks is essential for managing side effects, data fetching, and subscriptions.

3. State vs Props: State and props are fundamental concepts in React Native. State is local to a component and can be changed over time, while props are read-only properties that components receive from their parent. Managing state with the useState hook and passing data immutably through props are key practices to follow.

4. Flexbox: Flexbox is a layout model used in React Native for designing responsive UI components. It allows for flexible, responsive design without fixed dimensions, making it easier to build UIs that look good on any screen size or orientation.

5. Context API: The Context API provides a way to pass data through the component tree without having to pass props down manually at every level. This is particularly useful for data that needs to be accessed by many components throughout your application.

6. Redux: Redux is a state management library that can be used alongside React Native to manage complex, global application states in a predictable and efficient way. It's especially useful when you have multiple components that need access to the same pieces of data that change over time.

7. FlatList: For rendering lists of items, FlatList is the recommended component because it only renders items that are currently visible on the screen, which can lead to better performance with large datasets.

By understanding these concepts and becoming comfortable with them through practice, you'll be well on your way to becoming a React Native expert. Remember that the key to mastering React Native is consistent practice and real-world application of these principles.
