What is Required to Learn React Native?
React Native allows you to use your web development skills in developing mobile apps. If you are familiar with HTML tags then you can learn all the react native tags very quickly.

If you have experience with all these things, you are good to go. But, the most important thing than others is still missing.
How React Native Works?
In react native application, two threads run in the background at the same time. First, UI thread translates all the User Interface components to native platforms depending on the operating system on which the app is currently running. Let’s say you run the react native application on an android platform then your buttons and other widgets will be converted to android buttons. The same thing will happen on IOS and all the components will be translated to the IOS native components.
The other thread is responsible for handling all the business logic in the application. This thread is called JS thread. If a button in the application is used to open a new screen then all the code that is responsible for opening the new screen will be running in this thread. These two threads never communicate with each other directly and never block each other in processing.
How React Native Threads Communicate?
Both the UI and the JS thread communicate through a bridge. When a user interacts with the application and is required to do something based on that event, the UI thread will use a bridge to send instructions to the main thread. The main thread will run the code and then again use a bridge to communicate with the UI thread.
What is the Future of React Native?
