So the test expects false, but when you manually change it to expect true, it passes? Go figure indeed :P

The problem is that you have two 9s in b2, but only one 3 in b1 (you need to account for multiplicity too). If you "square" b1, you get [4, 4, 9], and that's not the same as [4, 9, 9].

I have 2 failing tests

Time: 1227ms Passed: 212Failed: 2Exit Code: 2

Testing for [2, 2, 3] and [4, 9, 9]
Log
isSame true
array2 element under test is 4 - sqrt is 2
array2 element under test is 9 - sqrt is 3
array2 element under test is 9 - sqrt is 3
expected true to equal false

and when i pass that into a test

    let b1 = [2, 2, 3];
    let b2 = [4, 9, 9];
    assert.isTrue(comp(b1, b2));

it passes - go figure :shrug

i can't even comprehend the maths in my head
