Narrowed return type of children()

[thetarnav]

Could the return type of children() helper be narrowed to not include ArrayElement & FunctionElement?
All the arrays and functions are recursively resolved to just Nodes/primitive values, so the types could reflect that. It would help with modifying elements, as there would be less types to worry about.
Something like this could work:

export type ResolvedElement = Node | (string & {}) | number | boolean | null | undefined
export declare function children(fn: Accessor<JSX.Element>): Accessor<ResolvedElement | ResolvedElement[]>;

edit: actually there is Exclude:

export type ResolvedElement = Exclude<JSX.Element, JSX.ArrayElement | JSX.FunctionElement>

They can still be arrays. But you are right, functions get resolved so see some potential here.

Do you mean it could return a nested array? What's the trick to that? 😅 I'm trying, but it always gets flattened perfectly.

Oh sorry I meant an array period.. not a nested one.. Gotcha.. you can just have resolvedElement | resolvedElement[]
