This section describes the conventions used here to describe type signatures.
A [T] is an array-like value (only ever used read-only in this API), i.e., one with an integer length and whose indexed properties from 0 to length - 1 are of type T.
A type T? should be read as T | undefined -- that is, an optional value that may be undefined.
