Z, the library used in the presentation

Promises in and out

The code in the folder promises-in-out demonstrates five different ways of writing code to achieve the same task. We assume that we can communicate with a blogging API via POST and GET requests and then do the following:

• Create a blog
• Create two blog entries
• Create some users
• Create some comments from those users, on the two posts
• Request the stats for the blog and check if the given number of entries and comments are correct

The code also contains a method called concatUrl which simply combines the given strings into an url path.

Promises between

In the folder promises-between there are examples on how Z does deep resolution, wraps functions to accept promises and enables mixins.
