>> I'm ready.
[00:00:20] Math.max called without any argument, will it be A Infinity, B -Infinity, C NaN, or D 10e25678?
>> I don't know, I'm thinking infinity would be my first go to, but without an argument, I'll go with C.
>> C, not a number, final answer?
[00:00:58] It thinks the difference between two not defined arguments, which is different than passing in undefined twice, will return -Infinity.
[00:01:28] So we're live on television. What are you thinking?
>> I don't know.
>> What would the length of a function be?
>> I'm thinking C.
>> C, why do you think it's C?
>> From a function in general, I'm not quite sure. It's just kind of a random guess, let's pop-
>> Random guesses are good. I like random guesses.
>> C, 2?
>> Final answer?
>> All right, you are correct.
>> Not the number of arguments passed or arguments used, but the arguments specified, so A and B.
[00:02:46] And remember, you do still have a lifeline.
>> This one feeling a little bit more confident with but not entirely. I know it's definitely not a number, so D, that's probably the obvious answer. I don't think it's gonna return A or B either because those are numbers, so, So it's either gonna be C or D.
[00:03:23] And I'll ask the audience.
>> All right, audience.
>> C or D.
>> So by round of applause, who thinks it's A? Who thinks it's B? Who thinks it's C?
>> Smattering, and who thinks it's D?
>> Different smattering. I'm not sure that that helped you a lot, sir.
>> Well, at least I know that I'm confident with C or D though.
>> The audience certainly agrees with you.
>> We'll go with C.
>> C, final answer?
>> It's A.
>> I think it's C.
>> Yes, final answer.
>> All right, "43". Unfortunately, it is the number 42 because the plus operator is not preceded by a string.
>> Hmm, we know it's equals to in Unicode, right, for a dot length?
>> Well, yeah, as we learned before, the length of each of these strings is two.
>> Okay. I don't know if you can subtract them though. So I'm thinking it's gonna be either C or D.
[00:05:17] I will go with C.
>> C, <Error>?
>> That's right.
>> I don't know, well, we know very few things throw errors.
>> It's very tolerant of whatever garbage you want to throw at it.
>> So we'll skip that one for now. I'm kinda feeling keep going with C here, but I'm thinking it's gonna be true for whatever reason because,
>> Why do you think it's gonna be true?
[00:06:46] You think it's gonna be a Boolean, I guess.
>> Well, yep, because it's empty so empty string, I think, does return false, am I right?
>> Okay. Yeah, so let's go with-
>> C true.
>> I don't know the argument explanation-
>> Well, unfortunately, I have a different answer on the next slide.
>> A lot of got yous.
