The other posts I've seen deals with 1D Arrays, so...

Array1

[
 ["PE","151"],
 ["PE","160"],
 ["PE","188"]
]

Array 2

[
 ["PE","193"],
 ["PE","173"],
 ["PE","188"]
]

Expected Result

[
 ["PE","151"],
 ["PE","160"]
]

I've tried using filter, but I'm not sure I can get the element to compare.

const newItems = Array1.filter(el => Array2[1].indexOf(el[1]) === -1)

Thanks!
