React Native is a very powerful and customizable mobile application development framework using Javascript. It allows you to incorporate most of the features that an application developed natively for each platform would offer. Development hours and costs are dramatically reduced as the application can be developed for both iOS and Android simultaneously. It gives more flexibility to the developer and allows for code re-usability, which in turn speeds up the app development process.

Reasons to use React Native?
- Cross-Platform: An important advantage of React Native is that you can develop an application for both Android and iOS ecosystems simultaneously by writing the same code with just a few modifications for each platform.
- JavaScript: There is no requirement to know the languages used for platform-specific application development, as React Native uses only JavaScript. It still is one of the most popular programming language right now, for the development of mobile applications.
- Performance: React Native enables speedy development of mobile applications since a similar code is used for applications for both platforms. It also facilitates a hot reloading feature that makes sure that small changes done to the application are immediately visible to the developer.
- Significant Developer Community: A big developers community ensures that all the queries are resolved in time and therefore, adequate support is available for the React Native framework.
- Improving Over Time: The aforementioned community also keeps updating React Native with new functionalities and making sure that bugs do not occur.
- Used by Large Corporations: Though the framework is somewhat new, many companies have already migrated the applications to this framework. Additional companies are looking to use the framework to speed up the process of development and maintenance.
- Career Opportunities: React Native popularity has grown over the last few years, due to advantages like cross-compatibility. Consequently, this popularity has led to a high demand and hiring for React Native developers.
