The event loop
the real event loop
-it is everywhere.
-everything wll eventually be written in it.
-threads vs events
keeps connections open by default
express - servers
connect - used by express
request - calling servers
Jade, Mu, ejs, eco....
Socket.io - connecting to stuff.
Tower.js - rails for node
asserting is built in to the framwork
testing framworks builds on that.
Nodmon - relods on save.
If you run it your self.... think of things.
