Problem Statement:

We are given an array containing numbers and arrays of numbers. We need to create a new array by converting all numbers to their square forms. We need to convert all numbers including numbers inside arrays.

For example- converting [34, [76, 12, 54], [90, 45, 13, 95], 43, 33] => [ 1156, [ 5776, 144, 2916 ], [ 8100, 2025, 169, 9025 ], 1849, 1089 ]

Code for Squares of array items in JavaScript:

myArr = [34, [76, 12, 54], [90, 45, 13, 95], 43, 33];
for(let i=0; i<myArr.length; i++){
  if(typeof myArr[i]==='number'){
    myArr[i] = myArr[i]*myArr[i];
  }else{
    result = []
    for(let j=0;j<myArr[i].length;j++){
      result.push(myArr[i][j]*myArr[i][j]);
    }
    myArr[i] = result;
  }
