# is array

This block is part of the [`condition`](https://docs.rual.nl/block-types/condition) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

checks if given inpin is an array

- Value required `value` The value to be checked.

- condition `condition` The condition that tells if the given value is an array or not.

True when the value pin holds an actual array, including an empty one; false for nil, missing, objects, numbers, and strings - JSON text like "[1,2]" is NOT parsed and yields false.

A typical wiring for [is array](https://docs.rual.nl/block-types/condition/condition_value_is_array): the `condition` out pin feeds [branch](https://docs.rual.nl/block-types/flow/branch).
