The following table shows the available datatypes for some systems. For W3C specs, I looked at the datatypes found in some of the presentation-oriented languages, particularly HTML, DOM, CSS, and SVG.

Datatype	Comment	JavaScript language	W3C specs	XSD Primitives Datatypes	JSON Schema	Google Gadgets
Datatypes found in JavaScript
string	-	Yes	Yes	Yes	Yes	Yes
number	-	Yes	Yes	Yes (presumably maps to a "double")	Distinguishes between "float" and "integer"	No
boolean	-	Yes	Yes	Yes	Yes	Yes (bool)
null	This may not be relevant to our discussion, but included here for completeness	Yes	No	? (not sure)	No	No
undefined	This may not be relevant to our discussion, but included here for completeness	Yes	No	No	No	No
arrays	-	Yes	Yes (NodeList)	Via custom types, but not primitives types	Yes	Partially. There is a list type that is a list of strings, unlimited length and dynamically growing
objects	-	Yes	Yes (elements)	Via custom types, but not primitives types	Yes	No
Datatypes in W3C specs (ignoring XML types(such as Element, Attribute, Node, NodeList, DOMImplementation, etc and things that are represented as objects)
