Collections

Collection objects store multiple values.

This group contains the general-purpose Expr containers and binary byte buffer object.

Collection Pages

Constructor	Page	Description
`array(…)`	array	Ordered list of Expr values.
`map(…)`	map	Ordered key/value map.
`data_array(…)`	data_array	Raw byte buffer with typed binary access.

Use `array` when order matters and values are addressed by numeric index.

Use `map` when values are addressed by string keys.

Use `data_array` when the content is binary data rather than normal Expr values.
