Javascript inheritance - the ultimate solution

Stop googling around. This is THE solution for javascript class inheritance unless you are using the Prototype framework

//Simply declare the following methods once:

Object.prototype.Inherits = function( parent )
{
 if( arguments.length > 1 )
 {
  parent.apply( this, Array.prototype.slice.call( arguments, 1 ) );
 }
 else
 {
  parent.call( this );
 }
}

Function.prototype.Inherits = function( parent )
{
 this.prototype = new parent();
 this.prototype.constructor = this;
}

//Then declare inheritance easily:

function Mammal( name )
{
 this.name_ = name;
}

Cat.Inherits( Mammal );
function Cat( name )
{
 this.Inherits( Mammal, name );
}

ColoredCat.Inherits( Cat );
function ColoredCat( name, color )
{
 this.Inherits( Cat, name );
}

Lion.Inherits( ColoredCat );
function Lion( name )
{
 this.Inherits( ColoredCat, name, "gold" );
}
