how to get the first item in nested, filtered array in javascirpt

Question

I've got an array:

const aContracts = [[ '0x8ae127d224094cb1b27e1b28a472e588cbcc7620', 0 ],
  [ '0xcbf4ab00b6aa19b4d5d29c7c3508b393a1c01fe3', 0 ],
  [ '0x03cd191f589d12b0582a99808cf19851e468e6b5', 0 ],
  [ '0x0b3f868e0be5597d5db7feb59e1cadbb0fdda50a', 1 ]]

And I'm trying to filter using the second item in each sub-array. So I used:

const aGoodContracts = aContracts.filter(contracts => contracts[1]===1);

And I get:

[["0x0b3f868e0be5597d5db7feb59e1cadbb0fdda50a", 1]]

However, I want [EDIT I want an array of all the "good" contracts]:

"0x0b3f868e0be5597d5db7feb59e1cadbb0fdda50a"

So I tried a solution I found here: const aGoodContracts = aContracts.map(k => k.filter(contracts => contracts[1]===1));

But I get:

[[], [], [], []]

What am I missing?

You can try this

const aContracts = [[ '0x8ae127d224094cb1b27e1b28a472e588cbcc7620', 0 ],
  [ '0xcbf4ab00b6aa19b4d5d29c7c3508b393a1c01fe3', 0 ],
  [ '0x03cd191f589d12b0582a99808cf19851e468e6b5', 0 ],
  [ '0x0b3f868e0be5597d5db7feb59e1cadbb0fdda50a', 1 ]]
const aGoodContracts = aContracts.filter(contracts => contracts[1]===1)[0]
console.log(aGoodContracts[0])
