+// Backwards-compatible iterator interfaces, augmented with iterator helper methods by lib.esnext.iterator in TypeScript 5.6.
+// The IterableIterator interface does not contain these methods, which creates assignability issues in places where IteratorObjects
+// are expected (eg. DOM-compatible APIs) if lib.esnext.iterator is loaded.
+// Also ensures that iterators returned by the Node API, which inherit from Iterator.prototype, correctly expose the iterator helper methods
+// if lib.esnext.iterator is loaded.
+// TODO: remove once this package no longer supports TS 5.5, and replace NodeJS.BuiltinIteratorReturn with BuiltinIteratorReturn.
+
+// Placeholders for TS <5.6
+interface IteratorObject<T, TReturn, TNext> {}
