Types

There are two main types of datatypes in Cosmo, primitives and references. Primitives exist directly in variables and tables. References are references to objects in memory, such as objects, tables, and functions. Objects are cleaned up and free'd by the garbage collector as soon as no references to the objects exist.

Primitives

Type	Description	Examples
Number	A numerical value.	255.0, 255, 0xff, 0b11111111
Boolean	Logical datatype	true, false
Nil	Represents an empty value	nil

References

Type	Description	Example
String	A string of characters	"ABC", "\x41\x42\x43", "\b1000001\b1000010\b1000011"
Object	A stateful data structure. See objects.md.	{x = 3}, proto Test end
Table	A generic data structure.	[1,2,3], [1 = "hello", "two" = "world"]
func	A callable routine.	function() print("Hello world!") end

There are some other reference datatypes that are used internally, however these will remain undocumented until they are accessible by the user
