React Native Interview Question

You can think of alignItems as justifyContent behaviour for cross-axis. Cross-axis in the case if React native is the horizontal axis. CSS alignItems property sets the alignSelf value on all direct children as a group. In Flexbox, it controls the alignment of items on the cross-axis. By default, the cross axis is horizontal in the case of React native. We can use this property to […]

JustifyContent property aligns the flexible container’s items when the items do not use all available space on the main axis. By default, the main axis is vertical in the case of React native. This means justifyContent property aligns child elements of flex parent vertically in React native. We can use this property to layout elements in a flex […]

CSS Flexbox is used to design responsive layouts easily, without relying on float or position CSS properties, which can be cumbersome. Introduced in CSS3, Flexbox ensures consistent layouts across different screen sizes.  In React Native, you typically use a combination of flexDirection, alignItems, and justifyContent to achieve the desired layout. There are some differences in the default values of […]

React Native follows the box model concept of CSS, where the size of an element is determined by its content, padding, border, and margin. The simplest way to set an element’s size is by specifying the width and height CSS properties. In React Native, all dimensions are unitless and represent density-independent pixels, ensuring consistent element sizes across different screen sizes when […]

The state is another way apart from props by which we can modify a React component. React component’s state value changes in the life cycle of the component, unlike props. We should not directly change the state value of the react component. React framework gives the setState method by which the state of a component should be changed.  The above code is an implementation […]

Integrating third-party libraries involves:  These steps ensure the library is correctly integrated and functional within the React Native app. 

Native Modules allow integrating custom native code into a React Native app:  Native Modules provide flexibility to leverage platform-specific features and optimize performance. 

Yes, React Native can be used for building TV applications:  While React Native supports TV app development, community support and documentation are still evolving. 

Managing app state can be done using:  Both tools enhance state management in large applications by handling asynchronous actions effectively. 

Keys in React Native are crucial for:  Keys should be unique to ensure React can manage component updates accurately.
