What Just Happened? How Did it Work?
Here's some insight on what's happening!
The main grammar rule??”SIZECRUST??”calls in the size and crust rules. In between,
it puts in items that may or may not occur in the input, like inch, and/or crust.
strcat is a function available in grammar XML that allows you to join two strings.
Note that there is no comma between the two arguments, and the order of execution
is from the innermost to the outermost.
Our JavaScript function takes a string and an index position.
