1. Faster to Build
The major selling point of React Native is shorter development time. It provides numerous ready-to-apply components that can accelerate the process. React Native still lacks some solutions, so you would probably have to build them from scratch. However, with the existing base of packages, you can save much time and it will only get better. As the RN community is growing and Facebook regularly introduces new updates, one day we may find a ready component for most of the solutions we need.
2. One Framework, Multiple Platforms
React Native enables copying the codebase (or just a part of it) between iOS and Android. In practice, full cross-platform development is possible to some extent, depending on how many native modules you use in your application. Some features will be available in apt packages, but others need to be written from scratch. It will only get better, though. React Native community actively supports the framework adding new tools to open source.
3. Hot Reloading
Thanks to hot reloading, a developer can keep the app running while implementing new versions and tweaking the UI. It makes changes in the app instantly visible without the need for the developer to save them. It is a major benefit for developers. Not only do they save time on the compilation, but also they don’t lose any state of an app while making changes. It boosts productivity and, in effect, the whole development time decreases.
4. Smaller Teams
5. Fast Applications
6. Simplified UI
React Native is solidly based on creating a mobile UI. In native development, it is necessary to create a sequence of actions in the application, whereas RN employs declarative programming in which such an order of implementing an action is obsolete. As a result, it is much easier to detect bugs on the paths a user can take.
