# phoneNumbers is array of 10 digit phone numbers, where the first three digits, in parentheses, are area codes.

Can't get it right. Please help. Excercise " phoneNumbers is array of 10 digit phone numbers, where the first three digits, in parentheses, are area codes. Using reduce, return the total phone numbers with a 503 area code. Store the total in the variable numberOf503."

```const phoneNumbers = ["(503) 123-4567", "(646) 123-4567", "(503) 987-6543", "(503) 234-5678", "(212) 123-4567", "(416) 123-4567"];
let numberOf503;

// numberOf503 should be: 3
numberOf503 =
phoneNumbers.reduce((count, number) => {
if (number.substring(0,4) === '(503)') {
return count +1;
}
return count;
});

console.log(numberOf503);
