I did console to track the test #, and also to see your code's output.

You are failing on the fixed test

assert.isTrue(determinant(m7)===88)

const m7 = [
  [2, 4, 5, 3, 1, 2],
  [2, 4, 7, 5, 3, 2],
  [1, 1, 0, 2, 3, 1],
  [1, 3, 9, 0, 3, 2],
  [1, 1, 2, 2, 4, 1],
  [0, 0, 4, 1, 2, 3]
]

where your code returns -88 instead of 88.

I hope that helps!

Would you show me your code?

Idk how to see it
