Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

The parent class for all array types (containers that are values)

This currently includes both Hack Arrays (vec, dict, keyset) and Legacy Arrays (varray, darray).
