 ### Use method chaining
 Against the advice of Clean Code, this is one place where we will have to differ.
-It has been argued that method chaining is unclean and violates the (Law of Demeter)
-[https://en.wikipedia.org/wiki/Law_of_Demeter]. Maybe it's true, but this pattern
-is very useful in JavaScript and you see it in many libraries such as jQuery and
-Lodash. It allows your code to be expressive, and less verbose. For that reason,
-I say, use method chaining and take a look at how clean your code will be.
-In your class functions, simply return `this` at the end of every function, and
-you can chain further class methods onto it.
