It's not weird, it's just beautiful, looking forward for your explanation.

First of all, nice video! and then, there're a couple that have explanation. For instance, ['1', '3', '11'].map(parseInt), the second argument of parseInt is in which base will take to do the conversion, I think by default is base 2 so 1 => 1, of course and 11 => 3, and finally, 3 in binary system does not exist that's why NaN. Another that I dare to explain is, 3 > 2 > 1 = false, (3 > 2) true (true is equal to 1) 1 > 1 (false) so true and false, false. It's quite confusing haha but understandable. See you! have a good day.

Wouldn't that one happen in most languages? For how I understand it, this statement checks if 1 is larger than 1.

i would build a programming language where null + null = 1, but null * 2 = null

[hamzacasdasdasd]

alr budy 0.1+0.2 happens on any languange !

[sgmvideos]

what is weird on that object + x is not a number?
.1 + .2 = .3000... not just in javascript, it's in any programming language that stores floating point number as 1.X * 2 ^ n
typeof NaN (not a number) being a number might seem strange, but it's just part of the object, which other object should it be under?
3 > 2 > 1 also not weird, works like this: 3 > 2 returns true, that is equal to 1, 1 > 1 is false... that is weird just to bad programmers.
typeof null being object is same as NaN, null is used when something should return object, but there is nothing to be returned
999... being 100... is the same thing as .1 + .2, javascript stores everything as double hence the moment number is too large, it has to round it

the rest is the stuff I watched this for

That's why Javascript was written in 10 days

[jcgamer]

I think NaN === NaN is false because you need to use strict types like NaN == NaN(JS is weird)

[VarunJain]

JavaScript is Not Weird, there is a reason behind it.

[maximsavenkov]

{} + “x” is Not a Number

javascript is confusing in mindustry: Groups.player.getByID().kick("reason", seconds*1000)
