ReQL command: [] (bracket)

Command syntax

sequence[attr] → sequence

singleSelection[attr] → value

object[attr] → value

array[index] → value


Get a single field from an object. If called on a sequence, gets that field from every object in the sequence, skipping objects that lack it.

Example: What was Iron Man’s first appearance in a comic?


The [] command also accepts integer arguments as array offsets, like the nth command.

Example: Get the fourth element in a sequence. (The first element is position 0, so the fourth element is position 3.)

r.expr([10, 20, 30, 40, 50])[3]
