javascript for...of loop to iterate over the multidimensional array

let studentsData = [['Jack', 24], ['Sara', 23],];

for (let i of studentsData) {
  for (let j of i) {
    console.log(j);
  }
}

javascript loop over three-dimensional array

var items = [[['firstName', 'Joe'], ['lastName', 'Blow'], ['age', 42], ['role', 'clerk']], [['firstName', 'Mary'], ['lastName', 'Jenkins'], ['age', 36], ['role', 'manager']]];

var result = [];
// first loop through items
items.forEach(function(item)
{
   var obj = {};
   // then loop through properties
   item.forEach(function (value)
   {
      // then set property and value
      obj[value[0]] = value[1];
   });

   // once all is done push the object
   result.push(obj);
});

console.log(result);

Iterating over a multidimensional array

var cubes = [["string", "string"], ["string", "string"]];

for(var i = 0; i < cubes.length; i++) {
    for(var j = 0; j < cubes[i].length; j++) {
        console.log(cubes[i][j]);
    }
}

create multidimensional array javascript for loop

var squares = new Array();
for(var i = 0; i <= 8; i++)
{
    squares[i] = new Array();
    for(var j = (i * 20) + 1; j <= 20 * i + 20; j++)
        if (squares[i] == null)
            squares[i] = j;
        else
            squares[i].push(j);
