Promises with Q.js
client = require './client_promises'
client.login('davide', 'pass').then ->
client.getPosts('alberto')
.then (posts) ->
cur = Q()
promises = posts.map (post) ->
cur = cur.then -> client.countPostLies(post)
Q.all(promises)
.then (results) ->
client.logout()
.catch (e) ->
console.error 'should handle error here'
- the code order matches execution order (big win)
- error handling is nicer because Q allows .catch at the end but we still need to manage different errors there
- we can also append .catch for each Promises for a more granular handling
- we still have to use closures (nesting) to serialize
client.countPostLike executions, in a hacky way
