How do I change the text of the 'Edit' button when I click on it?

I would like it to say "Done" when I go into edit mode and say "Edit" when it's not in edit mode.

Here is a snapshot of all of my code: https://w.trhou.se/8w7i1rnbmc

Hi there Zack,

I was just wrappin my head around this too and found a solution. I don't know if this is the intended/proper way to do it, but this is how I got it to work. I marked the code with comment arrows:

var editTask = function(){
  console.log("Edit task...");

  var listItem = this.parentNode;

  var editInput = listItem.querySelector("input[type=text]");
  var label = listItem.querySelector("label");

  var containsClass = listItem.classList.contains("editMode");

  // if the class of the parent is .editMode
  if(containsClass){
      // Switch from .editMode
      // label text become the input's value
    listItem.querySelector("button.edit").innerText = "Edit"; // <--------------
    label.innerText = editInput.value;
  } else {
      // Switch to .editMode
      // input's value becomes the label's text
    listItem.querySelector("button.edit").innerText = "Save"; // <-------------
    editInput.value = label.innerText;
  }

  // Toggle .editMode on the list item
  listItem.classList.toggle("editMode");
}

Hope this helps, if you don't understand wh/how this is working, feel free to ask.
