About Reloading in React Native

React Native is designed with an objective to give the best developer’s experience. The best thing is that it takes you between saving a File and understand the changes to it. So, how to manage these changes under a few seconds as your app grows? It can be achieved in three ways:

1. You can choose the JavaScript programming language having less accumulation cycle times.

2. You can implement a tool that can convert the multiple files into a simple JS format and easy to understand by Virtual Machine as well. It helps in managing changes much faster than your expectations.

3. You may add a feature Live Reload where the app is reloaded every time you save it.

Here are a some Fast Refresh tips:

• Fast Refresh preserves React local state in function components (and Hooks!) by default.

• If you need to reset the React state on every edit, you can add a special // @refresh reset comment to the file with that component.

• Fast Refresh always remounts class components without preserving state. This ensures it works reliably.

• We all make mistakes in the code! Fast Refresh automatically retries rendering after you save a file. You don't need to reload the app manually after fixing a syntax or a runtime error.

• Adding a console.log or a debugger statement during edits is a neat debugging technique.

It comes with an upgrade option where source files can be immediately upgraded to the forward version with minimum struggles. It internally finds files that should be removed, created, or modified.

So, how to do it using commands?  Start with the following command to upgrade to the latest version.
