3. Creating Interactive Front-End Pages
These applications load the resources as soon as the website is loaded which results in fast and responsive user interaction with great user experience.
Here is an image of a single page application.
Some examples of single page applications are Facebook, Google Maps, Gmail, Twitter, etc.
Two popular frameworks used for front-end application development are Angular and React.
Note: Angular is developed by Google and React is developed by Facebook. Hence, we can expect good and long support for this framework.
4. Creating Mobile Applications
One thing that is particularly interesting about React Native is that we can create both Android and iOS apps from the same codebase. This helps in:
- faster development time
- easy to develop
- cost effective
Some of the popular applications developed in react native are Facebook Ads, Walmart, Bloomberg, Instagram, Gyroscope, AirBnB, Myntra, UberEats, Discord, Townske, and many more.
