Are coroutines asynchronous Kotlin?

Await on an async is typically replaced with “withContext(yourProviderThread){} and then no await is required, but either way async { someMethod }. await() is acceptable, if you don’t await in line, then you can easily do one. await() + two . await() and that should give the same value as well.

How to write asynchronous function for Node.

If you use the async keyword before a function definition, you can then use await within the function . When you await a promise, the function is paused in a non-blocking way until the promise settles. If the promise fulfills, you get the value back. If the promise rejects, the rejected value is thrown.

Coroutines are Kotlin features that allow you to surround your blocking calls(Synchronous) codes in non-blocking(Asynchronous) constructs . A coroutine is like a function or a call which by default runs Asynchronously in parallel with others.

The first one is called async/await, available for the Swift programming language, and the second one is Coroutines, available for Kotlin . Our comparisons will be based on the iOS and Android development points of view.
