-If you read older texts on MVC, you may come across a description of models as also managing application 'state'. In JavaScript applications "state" has a specific meaning, typically referring to the current "state" of a view or sub-view on a user's screen at a fixed time. State is a topic which is regularly discussed when looking at Single-page applications, where the concept of state needs to be simulated.

 It is best practice to use `Model.set()` or direct instantiation to set the values of a model's attributes.
 
-Accessing `Model.attributes` directly is generally discouraged. Instead, should you need to read or clone data, `Model.toJSON()` is recommended for this purpose. If you would like to access or copy a model's attributes for purposes such as JSON stringification (e.g. for serialization prior to being passed to a view), this can be achieved using Model.toJSON(). Remember that this will return an object and JSON.stringify() should be used to get a string representation of the data:

 Sometimes you may also want to get a model based on its client id. The client id is a property that Backbone automatically assigns models that have not yet been saved. You can get a model's client id from its `.cid` property.

 * The order in which you append the sub-elements matters
 * The OuterView doesn't contain the HTML elements to be set in the InnerView(s), meaning that we can still specify tagName in the InnerView
-* render() is called after the InnerView element has been placed into the DOM. This is useful if your InnerViews render() method is sizing itself on the page based on the dimensions of another element. This is a common use case.
