View.mounted purpose?

1

I noticed view.mounted property and thought it would be a way to detect if the view.dom is actually part of the current page document, but it always is false.

What’s its real purpose?

From the constructor source

if (place) {
      if ((place as DOMNode).appendChild) (place as DOMNode).appendChild(this.dom)
      else if (typeof place == "function") place(this.dom)
      else if ((place as {mount: HTMLElement}).mount) this.mounted = true
    }

Where place is the element you want to mount in. Basically place can be an object with a mount property, if that’s the case you get that feedback you’re looking for.

Also, since this isn’t in the public, documented interface, as a general rule you shouldn’t worry about it when writing client code.
