  Another Typescript type, which is not included in the video, is the Pick<T> type, which is the opposite of Omit<T>. Instead of Omitting the property, you include the properties to be picked.

  updateTodo example has a bug... you need to prefix fieldsToUpdate with ... if you want to override the todo, otherwise you will create an object with additional fieldsToUpdate property, which contains the values that should be used for updating.

  The exclude util is not necessarily used for more complex types. It's for excluding types from union types in general instead of omitting props from an object type. So you could also use it to exclude e. g. string literals

  I'll never understand why interfaces hide their fields like it's something shameful lol. That Prettify type will save millions of developers including me.

  The Prettify type should not exist. It should be a typescript configuration option.
