I’ve been using Promises for some time now. JQuery has acted as a shim for some time, and several other libraries have been around as well. ES2015 includes Promises natively. If you’re unfamiliar with Promises, I strongly suggest you read this great post by Dave Atchley.
Today I want to talk about the value of ES2015’s new let and const variable declarations, and give you some use case scenarios. But first, let me tell you why I was really looking at all.

Sometimes, all of the planning in the world won’t stop a problem from occurring. Recently a piece of code deployed to production. It took a perfectly functional process and rendered it inert, no longer saving data that used to save. It wasn’t horrible, being caught fairly early, but people got upset.
