Thanks for clarifying. This is a very neat way of removing what would be an extra level of nesting. It doesn't look like native promises support this unfortunately: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... Another nitpick I have with native promises is that they require an extra level of nesting to get the resolve callback. // How it is now new Promise(function(resolve, reject) { resolve('done'); }); // vs. What most libraries implement var p = new Promise(); p.resolve(function() { return 'done'; });
