Navigator
A Navigator is a "location changer"; it's how you get to different locations.
Every history instance conforms to the Navigator interface, but the distinction is useful primarily when it comes to the low-level API where both the location and a navigator must be provided separately in order to avoid "tearing" that may occur in a suspense-enabled app if the action and/or location were to be read directly from the history instance.
interface Navigator {
createHref: History["createHref"];
encodeLocation?: History["encodeLocation"];
go: History["go"];
}
