script.js

let strs = ["abc" , "def",  "ghi"];
console.log(strs);
let strs2 = strs.map(item => {
   return item.split(''); 
});

let transposed = transpose(strs2);



const final = transposed.map(item => {
   return item.join(''); 
});
console.log(final);
function transpose(arr) {
    
  return arr[0].map((_, colIndex) => { 
      console.log(colIndex);
      return arr.map(row => {
          console.log(row);
          return row[colIndex]
