Web Reference: Feb 10, 2026 · A WeakMap is a collection of key/value pairs whose keys must be objects or non-registered symbols, with values of any arbitrary JavaScript type, and which does not create strong references to its keys. Apr 2, 2015 · WeakMaps provide a way to extend objects from the outside without interfering with garbage collection. Whenever you want to extend an object but can't because it is sealed - or from an external source - a WeakMap can be applied. The entries in a WeakMap are weakly held: if the object key becomes unreachable, its mapping is removed automatically. This is perfect for tracking data about objects without preventing garbage collection.
