Unfortunately Promises need to be fixed before fetch will be sane and here's how the promises spec currently looks: - unhandled errors silently swallowed [1] (this is the case for the most popular polyfill [1] too - the one recommended by fetch polyfills, BEWARE [3]) - no 'finally' method, despite pretty much everything in a UI needing some common 'cleanup' after e.g. a fetch() - not cancellable Right now you're better off with `$.ajax` (maybe make a custom build of jQuery) or a promise-like library like reqwest [2], rather than fighting with fetch.
