WeakMap.prototype.delete()

The delete() method of WeakMap instances removes the entry specified by the key from this WeakMap.

Return value: true if an entry in the WeakMap object has been removed successfully. false if the key is not found in the WeakMap. Always returns false if key is not an object or a non-registered symbol.

Parameters: key The key of the entry to remove from the WeakMap object. Object keys are compared by reference, not by value.

Syntax example: weakMapInstance.delete(key)
