[express]
$ express
do '# npm install -g express' beforehand, express command
generates nice template dir structure to get started
[code analysis]
# npm install -g jslint
$ jslint --sloppy --white <file.js>
[make a copy of an array]
var foo = [1, 2, 3];
var bar = foo.slice(0);
- an object that listen for event must be subclass of
of events.EventEmitter, e.g. http.createServer()
I'm an eventer, I will emit events, and have a list of
who responds/listens to those, so we will see statements
such eventer.on('foo', somehandler)
