If you want to clear something after you insert an input value; set inputtext.value = ''
If you want elements like buttons/images to appear on different line in HTML, <div> to separate into lines 
If you want to change certain index, you can access it like changeTodoPositionInput.value but .value will return string; but you can do .valueAsNumber, to make it number
  changeTodo: function(){
    var changeTodoPositionInput = document.getElementById('changeTodoPositionInput')
    var changeTodoTextInput = document.getElementById('changeTodoTextInput')
    todoList.changeTodo(changeTodoPositionInput.valueAsNumber, changeTodoTextInput.value)
  }
  
  One method of listing <ul><li></li></ul>
