/*
In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp 
server, but for some reason omit a client connecting to it.  I added an 
example at the bottom.

Save the following server in example.js:

# var xs = [1,2,3]
# doubleMe(doubleMe(doubleMe(xs)))
#這樣寫法有很多缺點，太多層次要把全部層次讀完才能知道最後結果。

#在墮性語言之中
#我們要做到調用 doubleMe 時並不會立即求值，它會說“嗯嗯，待會兒再做！”
#在真正執行時只會是一個平面，像 xs *2 *2 *2;

(a, b, c) --> a * b * c
#代替了

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

// Consider <Button /> is a pure render component
const AntiPureComponet = () => <div>
  Call me maybe?
  <Button><IconPhone /> Call</Button>
</div>

// When <AntiPureComponet /> renders, it creates a new child (by calling React.createElement) and pass to <Button />.
// This behavior forces <Button /> to re-render everytime.

Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.
