I do this frequently and I utilize their resume to power the code.

Someone says "I am a 9/10 in JS" I give them something that uses the animation frame api, the dom api, and a few more javascript APIs that I personally am not fully comfortable saying that I am a 9/10 on (been working with JS for over ten years) and see how they decipher what it is doing, what jumps out, and how they would review it / give feedback.

9/10 times they don't actually understand Javascript.
