Defined property `newTitle` on `TodosController` with default value of empty string. Without this, line `if (!title.trim()) { return; }` will throw _Uncaught TypeError: Cannot call method 'trim' of undefined_ when trying to submit an empty string.
Update the-rest-adapter.md

Plurals dealing with an API need to be underscored.
