Object-oriented and
Functional JavaScript
jason harwig

why so long?

1.

“JavaScript is the world’s
most misunderstood language”
- douglas crockford

2.

no classes

public class Presentation {
public static void main(String[] a) { }
}
7

3.

“No JavaScript”
- pointy-haired boss

why now?

classical inheritance through
libraries

“I want it to be web 2.0”
- pointy-haired boss

what do I need to know?

1.

JSON

var presentation = {
name: ‘oojs’,
};
19

var presentations = [
];
20

var presentation = {
name: ‘oojs’
};
21

abstract else int switch
as enum interface synchronized
boolean export is this
break extends long throw
byte false namespace throws
case final native transient
catch finally new true
char float null try
class for package typeof
continue function private use
const goto protected var
debugger if public void
default implements return volatile
delete import short while
do in static with
double instanceof super
22

2.

“prototype is like a rosetta
stone”
- brian dillard
jquery vs. prototype

3.

functions

functions as variables

functions without names

functions as constructors

functions vs methods

namespacing

objects

scopes

encapsulation

inheritance

no dot equals?!?

libraries

prototype.js

Presentation = Class.create({
initialize: function() { }
})

JQuery Classy Query

JavaScript 2.0
