Question 1

What is the basic component used to create containers in React Native?

Accepted Answer

The View component is the fundamental container in React Native, equivalent to a div in HTML. It allows grouping other components, applying styles, and managing layout via Flexbox. Unlike web, React Native uses View instead of div because it must be translated to native components (UIView on iOS, android.view on Android).

Question 2

What is the main difference between Text and View in React Native?

Accepted Answer

The Text component is the only component capable of displaying text in React Native. Unlike the web where any element can contain text, React Native requires all text to be wrapped in a Text component. View cannot contain raw text directly - attempting to do so generates an error.

Question 3

How to display a local image in React Native?

Accepted Answer

To display a local image in React Native, use the Image component with the source prop and the require() function. This approach allows the Metro bundler to resolve the image path at build time and optimize assets. Remote images use an object with a uri property instead.
