hasAnyJson<T, K>(value, key): value is T & object & View<K, AnyJson>
Tests whether a value of type T contains a property key of type AnyJson, using a shallow test for
AnyJson compatibility (see isAnyJson for more information). If so, the type of the
tested value is narrowed to reflect the existence of that key for convenient access in the same scope. Returns
false if the property key does not exist on the object or the value stored by that key is not of type
AnyJson.
