[SOLVED] Nesting For Loops: arr[i] is undefined?

JavaScript

Tell us what’s happening:

Your code so far

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

Hi @abdulrahmanmokhlef
