Inside server.js, let's make a variable called todo to do what we've done previously, creating an instance of a Mongoose model. We're going to set it equal to new Todo, passing in our object and passing in the values we want to set. In this case, we just want to set text.

app.post('/todos', (req, res) => {
  var todo = new Todo({
    text: req.body.text
  });

app.post('/todos', (req, res) => { var todo = new Todo({ ...
