Smart JS folks - this is why I can't pass the Google hiring test:
Given 2 to 3 arrays (it will either be 2 or 3, it can change), how would you return an array that only contains items in ALL the arrays.
Every solution I have found only seems to work w/ an array of simple values. I have an array of objects with a primary key, id.
Loop over number of arrays
For each item, output[item.id] = 1 if new else ++
Pool
Output all keys in output where value eq number of arrays
?
@falken ... i think that could work.

@raymondcamden when you get hired by Google I expect a kick back lol
@falken last time they called i said - happy to interview, no code test. they said, sorry, we have to do that, when can i schedule the call, i said, no thanks, bye.
That being said, I wouldn't mind ending up there in DevRel some day...
