{% apibody %} sequence[attr] → sequence singleSelection[attr] → value object[attr] → value array[index] → value {% endapibody %}
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?
r.table('marvel').get('IronMan')['firstAppearance'].run(conn)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]
40
