    }
}).getFromPath("food.fruits.apples");
//returns "red"

Hash Method: cleanValues

Arguments

  1. method - (function) The function that each value in the Hash is passed. If it returns true the value is kept. Defaults to $defined.

Example

$H({
    foo: 'bar',

$H({
    a: -1,
    b: 2,
    c: 0,
    d: -5
}).cleanValues(function(value){
    if ($type(value) != "number") return true;
    return value > 0;
});

Hash method: run

Runs all the methods that are values of the hash.

Syntax

Example

var myPage = {
    init: new Hash({
        setupNav: function(){
            //set up the nav
        },
        setupSearch: function(){
            //set up the search
