In C, the variable is a name that is used to make a piece of memory easier to use. When you assign a value to the variable, the value is stored into a piece of memory that corresponds to the variable name.

This means that upon storing a new value into the variable the old value is overwritten as the variable still references the same piece of memory. Generally, the first value isn't retained in any way that can later be accessed.

Now there are "exotic" ways of doing things that might not make this statement 100% true. There are Copy-on-Write systems (some of which are implemented in C) that do retain old values (in the general sense) when new values are written. However, these kinds of systems are not even present in the majority of C programs, and if you were using one, you'd know it.

As I understand it you are trying to identify all possible matches for the jumbled string in your list. You could sort the letters in the jumbled word and match the resulting list against sorted lists of the words in your data file.

You can add .drawingGroup() and it seems to resolve the issue without having to use the delay:

A little bit of conditional aggregation will do the trick.

resource, as well as request.resource point to documents, not collections.
While you can perform a get on a document path, you cannot do so on a collection.

So you will need to maintain the count of created patient for each user as a doc, for example in /users/uid add field patientCount. Then in your security rule you can check this field:

Maybe as an answer to reasoning – afaik, this is about not providing public API that goes agains semantics.

I.e. instantiating NoneType is something that you rather should not do, same as doing equality comparison for None.

If you have specific needs to build something dynamically – please provide them, usually there's an official API to do so (ast, as an example)

You have a useEffect hook that updates state: boroughs whenever value of state: boroughGroups changes.

In the return statement, you iterate through boroughs and update boroughGroups. Back to the first statement.

To stop this infinite loop, stop updating boroughGroups, that triggers useEffect everytime.

You have to pass callback parameter into func2 inside init. something like this.

{ employee: } it's invalid as a Hash. As you're trying to create a Hash with no value.

Try replacing it with just the symbol:
