chunk

array →
chunk(
    size: integer
) → array

Splits an array into consecutive, non-overlapping chunks of at most the specified size, preserving a final partial chunk. It resembles a count-based tumbling window but, unlike general sliding or hopping windows, has no separate step and always keeps the final partial chunk. It does not group items by inactivity or time. Returns null when the input cannot be evaluated.

Parameters

Name	Type	Required	Description
size	integer	Yes	The strictly positive number of items in each chunk.

Argument evaluation

• size: Evaluated once in the enclosing context.

Examples

{1, 2, 3} | chunk(2) → {{1, 2}, {3}}
