How to do Complete rest of the Todo UI in PouchDB?

Question

Complete rest of the Todo UI

todoBlurred is called when the user edits a document. Here we'll delete the document if the user has entered a blank title, and we'll update it otherwise.

function todoBlurred(todo, event) {
  var trimmedText = event.target.value.trim();
  if (!trimmedText) {
    db.remove(todo);
  } else {
    todo.title = trimmedText;
    db.put(todo);
  }
}
