Collection objects store multiple values.
This group contains the general-purpose Expr containers and binary byte buffer object.
| 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.
