Async Await is an actively used design pattern. In computer programming, the async/await pattern is a syntactic feature of many programming languages that allows an asynchronous, non-blocking function to be structured in a way similar to an ordinary synchronous function. It is semantically related to the concept of a coroutine and is often implemented using similar techniques, but is primarily intended to provide opportunities for the program to execute other code while waiting for a long-running, asynchronous task to complete, usually represented by promises or similar data structures. The feature is found in C# 5.0, Python 3.5, Hack, Dart, Kotlin 1.1, and JavaScript, with some experimental work in extensions, beta versions, and particular implementations of Scala, Rust, and C++..

Languages with Async Await include csharp, javascript

Example from csharp:

public async Task<int> FindPageSize(Uri uri) 
    byte[] data = await new WebClient().DownloadDataTaskAsync(uri);
    return data.Length;

Example from javascript:

async doSomething => await somethingElse()
