 Answer the following questions:
 
 What does `console` store?
+`console` stores the browser's debugging object. It contains methods such as `log`, `error`, `warn`, and `assert` that let us print values and inspect program state.
+
 What does the syntax `console.log` or `console.assert` mean? In particular, what does the `.` mean?
+The `.` is the property access operator. It means "look inside the `console` object and use the `log` or `assert` method stored there".
+So `console.log(...)` means “call the `log` method on the `console` object”.
+
+Try also entering `typeof console`.
+This returns `"object"`, because `console` is an object containing methods.
