Two unexpected Locals variables when iterating over array of containers.

[MimiKLM]

Hi,

I iterate over an array of containers. In the ForEach loop step variables format I have defined two variables; one is current offset, second one is current element.

The loop works fine.

However, during the debug process, I've spotted two new Locals variables called __ElementSibling0 (type: number) and __ForEachReleaser0 (type: obj. reference) created silently by TS as soon as I start iterating over my array. What are they?

Do they exist because:

1. I'm iterating over an array of containers, or
2. I use  the _currentElement_Freq variable, or
3. it always like that?

Those are used by the implementation of the For Each step. You can see them only because you have enabled the Show Hidden Properties setting.

You can safely ignore their presence.
