1.What is React Native?

A JavaScript framework, React Native is used for developing IOS and Android mobile applications. It allows building cross-compatible applications with JavaScript saving you from learning platform-specific languages like Swift and Kotlin for IOS and Android respectively.

The applications of React Native can be used in real mobile and is not a web applet.

2.Why Use React Native?

The reasons why you should use React Native are many.

• It is a cross-platform which lets you develop applications for Android as well as for the IOS systems. All you need to do is write the same code with just a few changes for each of the platforms.

• You are saved from learning different languages as React Native only uses JavaScript, which is also the most popular programming language.
• The framework allows quick development of the mobile apps since a similar kind of code is used to develop applications for both platforms. The hot reloading feature of React Nativeensures that even if there are small changes on the application, it is visible to the developer immediately.

• A large community of developers means that you can get all the queries solved in no time, which ensures optimism support at each stage.

• React Native gets better, and the community keeps updating the various functionalities, ensuring no bugs.

• The framework is not very old, but many companies have already embraced it and migrated to it as it helps to speed the process of maintenance and development.

• Its cross-compatibility makes it highly popular, which has also created a huge demand for React Native developers.

3.View, State, Props, and Style 

View

React Native has an elemental component called View that is used to build the user interface. The container supports the layout with style, flexbox, accessibility control, and touch handling. This maps to the native view directly, which is similar to the platform where the React Native app is running.

State

The React Native components are controlled by two data types which are the prop and the state. The state is used for those data that will change in the future. The state contains information of the data about the components. It determines what the behavior or the component is and how will it be rendered.

Props

Props stand for properties. The components can be personalized during creation using various parameters. It is these parameters that are known as props. Props get passed from one to the other container, which is like passing the data between themselves.

Style

React Native uses JavaScript to style the application. The core components of React Native make use of a prop which is the style. The value of the style is the same as the CSS, which works for the websites. 

4.React Native Apps vs Platform-specific Apps

Let us now go through the React Native and mobile applications that are specific to a platform.

• React Native is a cross-platform that works for both Android and IOS developers, whereas platform-specific apps are made only for the particular platform.

• The developers of React Native have a strong background in web development, and the platform-specific developers have good knowledge of the platform.

• The building time in React Native is fast and simple, whereas it is slow and complex in the platform-specific apps.

• The React Native apps are not recommended for the longer term and are best for small teams with limited development. The platform-specific apps are perfect as a longer-term investment and for those who have a lot of resources.

5.React Native Prerequisites

Here are the React Native prerequisites.

• Familiarity with the concepts of programming
• Basic JavaScript, CSS, and HTML knowledge

6.Industry Trends   

React Native has seen a surge in demand and is being adopted by many companies. Thus, there is the need for knowledgeable developers who are also paid handsomely compared to those working as front-end developers.

7.Create a React Native Application—To-do

Making mobile applications is called the To-Do. Here we list down the steps to create the React Native applications.

• Set an environment to develop the application
• Preview the app in real-time by installing the Expo app
• Visualize the app for components and as per the text editor
• Maintain the structure of the project
• Add the project components, ensuring it works as expected
• Tweak the functionality and design if required and appreciate the result

CONCLUSION

This brings us to the end of the discussion on the React Native tutorial. Create mobile applications for your Android and IOS phones with a single JavaScript language when you attend the React Native tutorial. This is beneficial as it saves a huge amount of money and time and eliminates the various stages associated with learning the development language for every platform.
