Introduction to React Native Interview Questions
Part 1 – React Native Interview Questions (Basic)
This first part covers basic React Native Interview Questions and Answers.
Q1. What is React Native?
Q2. Who Uses React Native?
There are many applications are built using the react native. Some of the listed below there are popular websites that are using the react native.
Q3. What is the Use of WebView in React Native?
WebView is a part of the React Native which is used to load a web page. It is supplied from the center of the library of reactors. The WebView is replaced by the built-in native of the central reaction and then inside the WebView library. WebView is a bridge linking web applications to the native respondent and provides users with various options to connect to the web-based program. You can also manage your browser and load an application to the web page from WebView. WebView is a React Native element that does not need to be enabled or configured.
Q4. What is Gesture Responder System?
The gesture response device controls the lifecycle of your application’s actions. The software decides what the user’s purpose is, and touch can go through many stages. For starters, you have to decide whether the touch scrolls, slides on a screen, or taps. During a brush, this can even change. Multiple concurrent touches can also exist. To allow components to manage these contact interactions without further knowledge regarding their parent or child portion, the touch response system has to be used.
Q5. How to Create a Button by Using the React Native?
React native provides a platform-specific Button component. This shows how we can build a basic platform button in Native react. The local device button means that the look and feel of a button depending on whether the program runs on IOS or Android. Title and onPress are two key advocates of the button part. Title props will be used on the button to display text. The callback is onPress props, triggered by the user when he presses the button. This is much like a web browser click case. We can’t design React native’s button part.
Part 2 – React Native Interview Questions (Advanced)
Let us now have a look at the advanced React Native Interview Questions.
Q6. How Virtual DOM Works in React Native?
React builds an in-home cache in the data structure, measures the variations resulting and then quickly updates the DOM shown on the browser. It enables developers to write code as if the whole page is displayed on each update when the React libraries just alter subcomponents.
Q7. How CSS Flexbox is Used to Layout a React Native UI?
The display in React native is set to flex by default. Flex is a CSS property that is used to dynamically expand and reduce a variable depending on the space available. The part takes up all the space available if you set flex:1. If a parent element has flex:1, then every element of its child must uniformly allocate the space available. By providing greater value to the flex property, we may adjust the width of the child item.
Q8. What is JSX?
Q9. Which React Native Tool and Skills you Need to Create the Mobile App?
Q10. What are the Advantages of React Native?
Props are parameters used at the time of design and restoration to configure a part. Proposals are like arguments passed to a part of a reaction. For instance, Image is a very fundamental component given for displaying an image in React Native library. It embraces a prop called source that regulates the picture that it shows. By modifying the values of props, a part may show different UIs and features. We may argue that props allow the same part in different areas to be used and re-used.
