Scoping

As a precursor to the ideas of components is automatic scoping. Anything declared within the .wlx script can be wrapped into a Module automatically. You can control this behavior using option

ProcessString[codeString, "Localize"->True]

codeString

Word = RandomWord[];
<Word/>

Word is unique every-time, when a string processor called.

Garbage collection

Unfortunately there is no clear way of purging the symbols created by Module, therefore they are collected into a symbol

JerryI`WLX`Private`garbageCollection

It is up to the user when and how clear them.

warning

There is no built-in method to purge unused symbols automatically, since symbols might be needed for the current connection or session, which 100% depends on your application.

The best option would be to have a certain even, that ends the "session" on which your code is subscribed. Then once it happens, on can purge all created symbols at once using pure function

Function[Null, 
	ClearAll[Word];
]
