promises: Abstractions for Promise-Based Asynchronous Programming
Joe Z. Cheng, Barret Schloerke, Winston Chang, Charlie Gao · 2018
Provides fundamental abstractions for doing asynchronous programming in R using promises. Asynchronous programming is useful for allowing a single R process to orchestrate multiple tasks in the background while also attending to something else. Semantics are similar to 'JavaScript' promises, but with a syntax that is idiomatic R.
