What is Kotlin coroutines

Here if you notice, we have used the async{} which returns an instance of Deferred<T> , which has an await() function that returns the result of the coroutine like we have future in Java in which we do future. get() to the get the result.

A coroutine is a concurrency design pattern that you can use on Android to simplify code that executes asynchronously . Coroutines were added to Kotlin in version 1.3 and are based on established concepts from other languages.

The main difference between them is that while Async/await has a specified return value, Coroutines leans more towards updating existing data .
