Firefox innerText undefined - Teacher's Note

Heads up if you are using FF you will experience an error in this stage as innerText is not implemented by Mozilla - There is a teacher's note that provides a work-around -- Thanks @Andrew Chalkley for including that note - I would have been lost without it.

Note additionally that the example is for the edit button but the delete and the label will also require the conditional as well.

if (typeof editButton.innerText === "undefined")  {
    editButton.textContent = "Edit";
  } else {
    editButton.innerText = "Edit";
  }

 if (typeof deleteButton.innerText === "undefined")  {
    deleteButton.textContent = "Delete";
  } else {
    deleteButton.innerText = "delete";
  } 

   if (typeof label.innerText === "undefined")  {
     label.textContent = taskString;
  } else {
    label.innerText = taskString;
  } 

If you're not worried about special character rendering or x-browser compatibility substituting innerHTML for innerText will work also.
