i thought that too! mega confused until i realized we were manually changing the length property.. object lengths are undefined... when array.from coerced it into an arr it managed to extract the length property, i was mistakenly thinking length was somehow going all the way to 0 on its own haha

Because if the length is 5, why would the length be 6? That is not logical...

appreciate the reply! but if Array.from() converts the argument given to an array, why does it stop at [5,4,3,2,1] with 5 elements instead of [5,4,3,2,1,0] ?

Because length-- decreases the value, but return the initial value. With --length, the result would be [4,3,2,1,0]

hmm.. why doesn't length go all the way to 0? if {length} is translated to {length: 5} and returns 5 then decrements, why does it turn into [5,4,3,2,1] ?

fantastic!

because with positives youre not meant to get the sum, youre meant to get the count of positive numbers , i.e. how MANY positive numbers appeared

bloody incredible mate

!= loose comparison is super cool...

not a group guys, if something is within brackets [] its called a range. a group would be chars surrounded by parenthesis e.g. (abcdef)

wow what on earth is this haha

really cool how (v ==='good') coerces to 1!

brilliant, thanks for commenting

super cool !
