 aUnspentTxOuts.find((uTxO) => uTxO.txOutId === txIn.txOutId && uTxO.txOutIndex === txIn.txOutIndex); 

Why is the equality between the unspent transaction id and the new transaction uxto reference id being checked for twice? Why can't you just do uTxO.txOutId === txIn.txOutId instead of uTxO.txOutId === txIn.txOutId && uTxO.txOutId === txIn.txOutId?

They might have wanted to say uTxO.TxOutIndex == txIn.TxOutIndex && uTxO.TxId == txIn.TxId
