Create Phone Number (6 kyu)

// Create Phone Number (6 kyu)
// https://www.codewars.com/kata/525f50e3b73515a6db000b83/

// Description:

// Write a function that accepts an array of 10 integers (between 0 and 9), that returns a string of those numbers in the form of a phone number.

// Example
// createPhoneNumber([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]) // => returns "(123) 456-7890"
// The returned format must be correct in order to complete this challenge.

// Don't forget the space after the closing parentheses!

// My Solution:

// (without regex)

function createPhoneNumber(numbers){
  let format = "(xxx) xxx-xxxx"
  for(let i=0; i<numbers.length;i++){
    format = format.replace("x", numbers[i])
  }
  return format
}

// (with regex)

// function createPhoneNumber(numbers) {
//     return numbers.join('').replace(/^(\d{3})(\d{3})(\d{4})$/g, '($1) $2-$3')
// }
