12. The point of promises is to give us back functional composition and error bubbling in the async world. ! The thing is, promises are not about callback aggregation. That's a simple utility… Promises
13. …More importantly, if at any point that process fails, one function in the composition chain can throw an exception, which then bypasses all further compositional layers until it comes into the hands of someone who can handle it with a catch. Domenic Denicola “You're Missing the Point of Promises” Promises
