Filter value contained in array in jq

Question

I want something like

jq 'select(.x in [2,4])' <<<'[{"x":1}, {"x": 2}, {"x": 3}, {"x": 4}]'
[{"x": 2}, {"x": 4}]

How do I do this?

Here's an efficient solution that has the advantage of also being simple and concise:

[2,4] as $list
| map(.x as $x | select( any($list[]; . == $x )))
