Promises for asynchronous programming

NOT ON THE CURRENT EDITION
This blip is not on the current edition of the radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the radarUnderstand more

The use of promises for asynchronous programming is an old technique that is also known as futures. It is gaining renewed interest in light of the extensive use of JavaScript on both the client and server side. This technique eliminates the use of deeply nested callbacks, flags and pollers and has first-class support from libraries such as jQuery. Teams developing JavaScript codebases of significant complexity should take advantage of this.
