Since we keep getting the `inputBox` from the DOM, what if we saved it as an attribute on the stringHandler, so other methods could access it?

Think of every time you select something from the DOM, either by getElementById or querySelectorAll or whatever, it's doing a `select` on a database. If you run it once and assign it to a variable, then you can just access the element over and over without querying the DOM. This is a concept known as _caching_ and it's a fun problem :).
