Alternative solution for coins !

Hi ! thank you very much for you amazing tutorials !

Here is my solution for the coins

```
function getChange (totalPayable, cashPaid) {

var result = [];

var coins = [200, 100, 50, 20, 10, 5, 2, 1];

var diffrence = cashPaid - totalPayable;

var i = 0;

do {
if (coins[i] <= diffrence)
{
result.push(coins[i]);
diffrence = diffrence - coins[i];
}
else
i++;
}
while (i < coins.length);

return result;
}
```

The issue contains an alternative JavaScript getChange solution but names no repository file, exercise location, or requested change. Start by reviewing the coins tutorial and its existing tests, then determine whether this example should be incorporated and what acceptance criteria would apply.
