// Objective
// In this challenge, we practice using arrow functions. Check the attached tutorial for more details.
// Task
// Complete the function in the editor. It has one parameter: an array, . It must iterate through the array performing one of the following actions on each element:
// - If the element is even, multiply the element by 2.
// - If the element is odd, multiply the element by 3.
// The function must then return the modified array.

function modifyArray(nums) {
  let newArray = [];
  nums.map((num) => {
    num % 2 === 0 ? (num *= 2) : (num *= 3);
    newArray.push(num);
  });
  return newArray;
