The way Javascript deals with strings is entirely different to the way PHP
does. In Javascript, strings are an immutable object, so the += operator
doesn't just concatenate one new string onto an existing string object --
it creates a brand new string object then reassigns the old string object
variable to point to the new object, marking the old object for garbage
collection.
