Nesting For Loops!

JavaScript

Tell us what’s happening:
Sorry, I’m looking at this code for an hour and can’t understand why it’s not working.

Your code so far


function multiplyAll(arr) {
  var product = 1;
  // Only change code below this line
  for (var i = 0; i < arr.lenght; i++){
    for (var j = 0; j <arr[i].lenght; j++){
      product *= arr[i][j];
    }
  }
  // Only change code above this line
  return product;
}

// Modify values below to test your code
multiplyAll([[1,2],[3,4],[5,6,7]]);

i figured it out but one thing i mess up on was that i defined the arr which i didn’t have to do because the parameters/arguments below are defined for me already…damn it

Use the debugging tools : you would have found it immediatly
