What does ts swear at if he specified the correct interface?

Question

typescript

I can’t understand what the TS requires of me when I pass the interface to it on the item that lies in the callback. Checked, in the console room === IRoomItem, but the vehicle still does not skip. If I put any, then everything is fine (strange, yeah)

Answer 1

Try it differently:

Object.values<IRoomItem>(this.props.rooms).map( /* */ );
