# Can anyone find my errors because I can't do that

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.

app.js
const phoneNumbers = ["(503) 123-4567", "(646) 123-4567", "(503) 987-6543", "(503) 234-5678", "(212) 123-4567", "(416) 123-4567"];
let numberOf503;
numberOf503 = numberOf503.reduce((count, number) => {
if(number[0] === '503'){
return count;
}
}, 0);

// numberOf503 should be: 3

number[0] will search for the first character only. I used .slice() method, but you can use .startsWith() method or .substring() method. There are many ways :) Hope this help!

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

numberOf503 = phoneNumbers.reduce((total, phoneNumberString) => {
if (phoneNumberString.slice(1, 4) === "503") {
total++;
}
