Function that transposes two strings from top to bottom instead of left to right within an array

My current challenge involves transposing two strings vertically instead of horizontally using javascript. I'm contemplating whether to employ the map() and slice() methods for this task. The input will be an array containing two strings, and my goal is to create a function that arranges these strings from top to bottom.

For example, if given ['Hello', 'World'], the output should be:

H W
e o
l r
l l
o d

Here are some important points to consider:

- There should always be one space between each pair of characters. - The case of the characters should remain unchanged, no need to convert to upper or lower case. - If one string is longer than the other, a space should be inserted in place of the missing character.

Updated as I overlooked the condition where the strings may differ in length:

let exampleArray = ['Hi','There'];

function reorganize(array) {
  let finalResult = '';
  let index = 0;
  while(array[0][index] || array[1][index]) {
    finalResult += array[0][index] || ' ';
    finalResult += ' ';                            // add space if desired
    finalResult += array[1][index] || ' ';
    finalResult += '\n';
    index++;
  }
  return finalResult.slice(0, -1);
}

reorganize(exampleArray); // results in:
                              "H T
                               i h
                                r
                                 e"
