Tuple
Tuples may contain mixed data types, which define its shape:
<1, 'pizza', 3.14> // the shape is <number, string, number>
Nested tuples
Tuples may be nested in other tuples, and each one can have a different shape:
<
<1, 'pizza', 3.14>,
true,
@/some/file.joe,
1 .. 3,
<1, 2, 'fizz', 4, 'buzz'>
>
Conditional items
Unfortunately, tuples do not support conditional items like arrays do, as it would cause the shape to be invalid.
Alternatively, a ternary may be used
<
1,
someCondition ? 'burnt-orange' : '', // will always be defined, so the shape is correct
true
>
Tuple Types
Tuples can be used as types:
// variable declaration
let foo: <bool, number>;
// function parameter
f foo (bar: <bool, number>) {}
// return type
f foo -> <bool, number> {}
// array of tuples
<bool, number>[]
