Fluff 2012 August Notes on Advanced Javascript

I just attended the NFJS Raleigh tour stop. This was my third time at this great event and my focus of the sessions was javascript and mobile.

Here begins my notes:

Suggested Book: Seven Languages in Seven weeks by Bruce Tate

Prototypes – IO, LUA, SELF : access to class , define on the fly, manipulate class after you define it.

Functional JS vs OO JS

http://joda-time.sourceforge.net/ – spring data

Everything in javascript is an object but primitives.  Objects consist of key value pairs + prototype

javascript function is pass by reference not by copy.

Dynamic typed language

hoisting –  Only functions create a new scope.

propertyIsEnumerable : higher within prototype

passing functions to a function desirable for reuse

associative array {name: ‘fred’}

two scopes: global and function level scope

this – scope you are in

null == undefined

parasitic inheritance is like composition

CommonJS – use of require

Underscore.js

Date.js

Sugar.js

Backbone.js

Testing- Jasmine
