A boring function (6:22)

func boring(msg string) {
  for i := 0; ; i++ {
    fmt.Println(msg, i)
    time.Sleep(time.Second)

Promises reading list

This is a list of examples and articles, in roughly the order you should follow them, to show and explain how promises work and why you should use them. I'll probably add more things to this list over time.

This list primarily focuses on Bluebird, but the basic functionality should also work in ES6 Promises, and some examples are included on how to replicate Bluebird functionality with ES6 promises. You should still use Bluebird where possible, though - they are faster, less error-prone, and have more utilities.

I'm available for tutoring and code review :)

You may reuse all gists for any purpose under the WTFPL / CC0 (whichever you prefer).

The Pledge

One thing that always made me a little sad about transducers was how map lost its ability to iterate multiple collections in parallel. This is actually my favorite feature of map. For example:

(map + (range 5) (range 5 10))
=> (5 7 9 11 13)

One somewhat practical use of this is if you want to compare two sequences, pairwise, using a comparator. Though I wish that every? took multiple collections, this is an adequate substitute:
