Question: adding a custom variable name instead of harcoded properties name

[alaa-paramount]

hi guys,

I'm facing the following situation:

testVar = "abc";

makePersistable(
    this,
    {
	    properties: ['testVar'],
	    // rest of stuff
    }
);

I'm trying to pass a variable name to 'properties', but it's not working,
also, I've tried to do it like the following code but it didn't work:
properties: [Object.keys(this.testVar)[0] as keyof this],

my goal is to not hardcode strings inside properties[]
any suggestions?

Can you add an https://codesandbox.io/ example of what you are trying to do and I can look at it.

Thanks @codeBelt,

here's the codesnadbox:

file: TodoStore.ts
scroll to line 21:
properties: ["activeNote"]

my goal is to make it work with variable, something like this:
properties: [this.activeNote]

    makePersistable(this, {
      name: 'ChangeAddressStore',
      properties: Object.keys(this) as (keyof this)[]
    })
