I appreciate the brevity of the shorthand 🤷

const foo = () => ({ a: 1, b: 2 });

compare that to:

const foo = () => {

@breakingthings's promise advice

How not to suck at $q

1. success / error are not promise flow. They're pseudopromise demons. Use then and catch instead.
2. $q.defer is satan. You should basically never use it. There is an alternative syntax that is superior, $q(function(resolve, reject) {}) but chances are that what you’re working with already returns a promise, and if it does there is absolutely no need for either of these.
3. Don’t use the promiseFn().then(successFn, errorFn) pattern, as errorFn will only catch errors caused by promiseFn, but not by successFn. Use then(successFn).catch(errorFn) instead. Also note that you can chain several thenables and catch all of them this way, ala then(a).then(b).then(c).catch(errorFn), in which errorFn will handle errors that happen for any of a, b, or c.
4. Whatever you return from a then-able is turned into a resolving promise. Whatever you throw is turned into a rejecting one. For instance, `.catch
