In this React Native video lesson we want to learn about AsyncStorage in React Native, AsyncStorage is a module in React Native that provides simple, asynchronous, persistent and key value storage system. it allows developers to store and retrieve data in a persistent manner similar to the way cookies or localStorage work in web development. AsyncStorage is commonly used in React applications for storing user preferences, app settings, and other small pieces of data.

AsyncStorage provides simple API that allows developers to:

• Save key-value pairs to disk asynchronously
• Retrieve a value for a given key asynchronously
• Remove a value for a given key asynchronously
• Get all keys stored asynchronously
