#Play2 : Les Iteratees expliqués aux humains... francophones!

Disclaimer : Ce qui suit est la traduction d'un article anglophone paru sur le blog mandubian.com

Vous pouvez retrouver l'article original ici

Vous avez probablement remarqué une nouvelle fonctionnalité intrigante de Play2 nommée Iteratee (ainsi que ses compagnons Enumerators et Enumeratee). Le but de cet article est d'essayer de rendre le concept d'Iteratee compréhensible pour le plus grand nombre avec des arguments simples, en évitant l'approche mathématique / fonctionnelle.

Cet article ne prétend pas tout expliquer à propos des Iteratee / Enumerator / Enumeratee mais traite plutôt les idées qui se cachent derrière.

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Many of my friends have shared their reading lists of all the books they read in 2014 (thank you!) -- this gave me some excellent ideas of books to read for 2015.

So I have decided to share my reading list as well, and the list of books I plan to read in 2015. If you have any ideas for additional books, I'd love them (especially in the topic areas of business, finance, nonfiction).

Favorite books I read in 2014:

The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers by Ben Horowitz
The Everything Store: Jeff Bezos and the Age of Amazon by Brad Stone
The Effective Executive: The Definitive Guide to Getting the Right Things Done by Peter F Drucker
Zero to One: Notes on Startups, or How to Build the Future by Peter Thiel

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).
