When we talk about a type in TypeScript, we mean a collection of things that you can do with a variable (or expression). You might be able to read or write a given property, call a function, use the expression as a constructor, or index into the object. Some objects (like Date) in JavaScript can do nearly all of those! In TypeScript, interfaces are the most flexible way of describing types.
