Hey guys. This issue is almost 3 years old at this point. Could you please clarify if the promises returned by the Delighted API calls also have a catch callback? I'd like to use the async/await syntax and it's not clear whether try/catch(error) would get triggered correctly, based on the examples provided in the README.md.

Thanks!

@andreimarinescu The library does not currently provide catch callbacks:

$ node
> var delighted = require('delighted')('KEY')
undefined
> delighted.person.create({}).then(function() { console.log('ok') }, function() { console.log('fail') })
{ then: [Function: bound then] }
> fail
> delighted.person.create({}).then(function() { console.log('ok') }).catch(function() { console.log('catch') })
TypeError: delighted.person.create(...).then(...).catch is not a function

It's on the roadmap to add this but no ETA currently I'm afraid.
