Returns true if the passed in value/object is defined, that means is not null or undefined.

Arguments

Returns the type of object that matches the element passed in.

Arguments

Example

var myString = 'hello';
$type(myString); //returns "string"

Returns

function $merge()

merges a number of objects recursively without referencing them or their sub-objects.

Arguments

any number of objects.

Example

var mergedObj = $merge(obj1, obj2, obj3);
//obj1, obj2, and obj3 are unaltered

var $extend = function()

Copies all the properties from the second passed object to the first passed Object.  If you do myWhatever.extend = $extend the first parameter will become myWhatever, and your extend function will only need one parameter.

Example

var firstOb = {
    'name': 'John',
    'lastName': 'Doe'
};
var secondOb = {
    'age': '20',
    'sex': 'male',
    'lastName': 'Dorian'
};
$extend(firstOb, secondOb);
//firstOb will become:
{
    'name': 'John',
    'lastName': 'Dorian',
    'age': '20',
    'sex': 'male'
};

Returns

The first object, extended.

var $native = function()

Will add a .extend method to the objects passed as a parameter, but the property passed in will be copied to the object’s prototype only if non previously existent.  Its handy if you dont want the .extend method of an object to overwrite existing methods.  Used automatically in MooTools to implement Array/String/Function/Number methods to browser that dont support them whitout manual checking.

Arguments

a number of classes/native javascript objects

Returns true if the passed in value/object exists or is 0, otherwise returns false.  Useful to accept zeroes.

Arguments

function say(msg){
    alert($pick(msg, 'no meessage supplied'));
}

Returns a random integer number between the two passed in values.

Arguments

Returns

a random integer between min and max.

function $time()

Returns the current timestamp

Returns

a timestamp integer.

clears a timeout or an Interval.

Returns

null

Arguments

var myTimer = myFunction.delay(5000); //wait 5 seconds and execute my function.
