How can I complete this task ? Thanks!
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
// Write your code below
numberOf503 = phoneNumbers.reduce( number => {
if(number === charAt(503){
return numberOf503;
}
})

Treehouse TeacherHey Azzie Fuzzie the charAt method will return the characters at a given index. It looks like you're attempting to check if the numbers start with 503 using the
charAt()method. Try instead using a method like substring then inside your return statement, make sure you returnnumberinstead ofnumberOf503
