How to make a record shorter?

Question

typescript

public pin(object: PinnedObject): void {
    object.pinned = !object.pinned;
    object.date = new Date();
  }

How to write this record shorter and more beautiful?

Maybe so, but how good is it?

function pin(object: PinnedObject): void {
    object = { ...object, pinned: !object.pinned, date: new Date()}
  }

"You can not do it this way. Because this new objectmethod will not go anywhere and will be collected by the GC.
In general, the existing record does not require any changes. Actions are taken in the same way. There is nowhere to improve and there is nothing.
If there were a whole bunch of assignments, one could think of Object.assign, but here it is definitely not worth it and will only worsen readability.
