O Language/API/Types

Types

O Language values are dynamically represented at runtime.

Value	Example	Description
Integer	42	Signed whole number.
Float	3.14	Floating-point number.
Boolean	true	Boolean value.
String	"O Language"	Text value.
Array	[1, "two", true]	Ordered, zero-based collection.
Hash	{"name": "O"}	Key/value collection.
Function	fn(x) { return x + 1 }	Callable value.

The runtime also exposes system values for processes, environments, sockets, database connections, models, routes, requests, signals, modules, closures, compiled functions, and errors.

Indexing

def items = ["first", "second"]
output(items[0])

def user = {"name": "Ada"}
output(user["name"])
