Variables

rev20211113

Declarations and Assignments

Variables are declared using var and assigned using =.

var x: int = 42
x = x / 2
assert(x == 21)

If no type is specified, the type is inferred.

var s = 'value'
assert(typeof(s) == 'string')

A variable declared without assignment are initialized with default value.

var n: int
assert(n == 0)

You must specify the type or assign value.

var n // ERROR

Cotowali supports multiple variables declaration and destructuring assignment using tuple.

var (a, b): (int, int) = (1, 2)
assert a == 1 && b == 2
(a, b) = (b, a)
assert a == 2 && b == 1
