explain javascript prototype

[smcalilly]

When you introduce the concept of an object I found it helpful to play around with sayHello in the repl to when following along the Mozilla article you link to. Might want to add a real illustration here where the reader runs object.getPrototypeOf(sayHello) and sayHello.prototype. That drove home what a prototype is for me. It's like a template for an object. A prototype is like a "class" in Ruby I think. At least it seems like the same concept as something like say_hello.class which if you went far enough up the chain ruby you'd arrive at method the same way sayHello.prototype returns function
