Methods can be any function, they could take arguments, maybe they won't take arguments, and to define them all we do is the following. Without adding a comma, another quirk of the class syntax, we specify our method name. I'm going to create one called getUserDescription:
getUserDescription () {}
This one is not going to take any arguments so we can leave that arguments list empty. Inside the function itself, we're going to go ahead and return a description, since the method after all is called getUserDescription. We're going to return a template string injecting some values inside there, the general flow is going to be Jen is 1 year(s) old:
getUserDescription () { return `Jen is 1 year(s) old`;}
This is what we want ...
