Chaining promises

Chaining promises in ClojureScript is best done using the thread-first macro, ->. Here's an example of using the fetch API:

(-> (js/fetch "/data")
    (.then (fn [r]
             (when-not (.-ok r)
               (throw (js/Error. "Could not fetch /data")))
             (.json r)))

Prologue

I wrote this answer on stackexchange, here: https://stackoverflow.com/posts/12597919/

It was wrongly deleted for containing "proprietary information" years later. I think that's bullshit so I am posting it here. Come at me.

The Question

Amazon is a SOA system with 100s of services (or so says Amazon Chief Technology Officer Werner Vogels). How do they handle build and release?

The Sustainable Dream

Criteria:

Emphasize environmental stewardship and sustainable living
Prioritize clean energy and zero-waste practices
Focus on community building and local, cooperative economies
Value a work-life balance with reduced working hours
Encourage eco-friendly transportation alternatives

An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

Zoom Code Review

===============

Why Code Review?

The most effective way to get bugs out of code is code review. More than running the code, more than unit tests, having someone else review an author's code is the best technique known to eliminate bugs (Fagan 1975 and Cohen 2006).
