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

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] ?

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 !
