Front End Web Development Techdegree Student 21,661 PointsUnable to pass array.reduce challenege
I been trying to get my head around it but failing to do so, here is my code
const phoneNumbers = ["(503) 123-4567", "(646) 123-4567", "(503) 987-6543", "(503) 234-5678", "(212) 123-4567", "(416) 123-4567"];
phoneNumbers.reduce((count, numbers)=>{
if(numbers[1] === 5){
console.log(count + 1)
}else{
//console.log(numbers[1]);
}
},0)
But I cannot pass it for some reason
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

231,126 PointsYou seem to have the right idea but a few issues. Here's some hints:
- leave the comments and write your code below them
- the result needs to be stored in the "numberOf503" variable
- a type-sensitive compare of a number and a string will always fail
- you don't need to log anything
