Questions about JavaScript libraries

[aspnetguy]

I've been looking at some libraries lately (mainly dojo) and have a few questions I hope someone can answer.Firstly what does this mean?

var dojo = {};

I have seen var arr = []; used to define an array but not {}.Also I can't seem to understand what this is doing or what it means

dojo.version = {	// summary: version number of this instance of dojo.	major: 0, minor: 4, patch: 0, flag: "",	revision: Number("$Rev: 6258 $".match(/[0-9]+/)[0]),	toString: function(){		with(dojo.version){			return major + "." + minor + "." + patch + flag + " (" + revision + ")";	// String		}	}}

What is with the major: 0, minor: 0, etc and again there is the dojo.version = {...}, I assume the variable: value and {} are related but am not sure how.thanks

this is the shortcut for creating a new objectvar dojo = {} is the same as var dojo = new Object()

Thanks,Any idea about the major: 0, minor: 0 stuff inside the object?Is that methods and properties of the object???

I did some testing and it is indeed how to define methods and propertiesa:0 is the same as this.a = 0example

var obj = {  param1: "hello"}alert(obj.param1) //pops up "hello"

its like this:var cur = {$1: "test",$2: "test2"}andvar cur.$1 = "test"; var cur.$2 = "test2";and you use them by eithercur.$1 or cur['$1']you can also use functions=P
