    In JS

    function modifyArray(nums) {
    const res = nums.map((val) => {
  if (val % 2 == 0) {
    return val * 2;
  } else {
    return val * 3;
  }
});

return res;

}

    Managed to fit in one line:

    function modifyArray(nums) {
    return nums.map(n => n % 2 ? n * 3 : n * 2);
}

          function modifyArray(nums) {
  for (let i = 0; i < nums.length; i++) {
    if (nums[i] % 2 === 0) {
      nums[i] = nums[i] * 2;
    } else {
      nums[i] = nums[i] * 3;
    }
  }
  return nums;
}
