Knowing the balance 

The next thing that we want to do is to cycle through the addressTransactions array to figure out what the balance of the address that we are searching for is. In order to know the balance:

let balance = 0;

2. Next, we want to cycle through all of the transactions inside of the addressTransactions array. We will do that with the help of the forEach loop as follows: 

let balance = 0;addressTransactions.forEach(transaction => { });

let balance = 0;addressTransactions.forEach(transaction => {        if (transaction.recipient === address) balance += transaction.amount; else if (transaction.sender ...
