implement a three nested loop in Javascript

  for (let i = 0; i < 3; i++) {
    for (let j = 0; j < 3; j++) {
      for (let k = 0; k < 3; k++) {
        console.log(i, j, k);
      }
    }
  }

This code is a three nested loop in Javascript. The outermost loop is represented by for (let i = 0; i < 3; i++), meaning it will loop from 0 to 2 with the increase of one on each loop. Inside this loop, we have the second loop for (let j = 0; j < 3; j++) which will run from 0 to 2. The innermost loop is for (let k = 0; k < 3; k++), which will also loop from 0 to 2 in the same manner as the previous two loops. The console.log(i, j, k) statement will allow us to see the output of the combination of i, j and k on each loop. In other words, the three nested loop will run 3 x 3 x 3 = 27 times in total and each time it will log to the console the combination of i, j, and k.
