I was surprised by that too. Maybe they allowed free-form answers.
No, it was a checkbox array (I took the survey). The thing is, saying you use jQuery is not the same as saying you use Javascript. The only Javascript I really use is jQuery. I have no deep JS needs, so I only use jQuery to make interfaces pretty. I chose jQuery (and C#, and some others) but did not choose JS.
Not a big deal it just seems odd to me. At least they didn't put HTML up there :)
