For all the people who say the questions are pedantic, I agree – but I would also say that misses the point. Each question focuses on an important characteristic or quirk of JS. Surely knowing these is important.

@kangax – Fascinating stuff, but I too think it borders on the pedantic. I also don’t think a good developer is only someone who knows all the answers to these: people on top of all these answers aren’t writing javascript themselves – they’re writing blog posts about how well they know it (or how awesome they are)! :)

it is a shame that the programming language that may well be the best-deployed programming language of all times is full of unscrutinable reasoning, unreasonable plumbing, and outright bugs, on top of an interpretation of object-orientation that requires an expert to avoid the most obvious pitfalls.

the language that drives billion of webpages should be easy to learn, easy to grasp, and easy to read. javascript’s score on each dimension is appalling. at least it seems to have become rather fast of late.

@thnkfstr I’ll explain in the upcoming post (that also provides and explains answers) why this quiz is useful. As far as `typeof typeof …`, you really don’t even need to know what happens in first line. `typeof` always returns string (even for host objects), so `typeof typeof …` obviously always results in “string” ;)

neat quiz, but borders on pedantic rather than useful. I’m not sure I’d hold it against a dev if they couldn’t tell you what the result of the following is:

var x = [typeof x, typeof y][1];
typeof typeof x;
