/*
--------------- 6 Kyu - Create Phone Number
 ------------------

Instructions:

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!

-------------
Sample Tests

const chai = require("chai");
const assert = chai.assert;
chai.config.truncateThreshold=0;

describe("Create Phone Number", () => {
  it("Fixed tests", () => {
    assert.strictEqual(createPhoneNumber([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]), "(123) 456-7890");
    assert.strictEqual(createPhoneNumber([1, 1, 1, 1, 1, 1, 1, 1, 1, 1]), "(111) 111-1111");
    assert.strictEqual(createPhoneNumber([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]), "(123) 456-7890");
  });
});

--------------

Psuedo Code:

use .slice() and template literal to return the phone number with parentheses and spaces

*/

function createPhoneNumber(numbers){
    return(`(${numbers.slice(0, 3).join('')}) ${numbers.slice(3, 6).join('')}-${numbers.slice(6, 10).join('')}`)
}
