-# jest-leak-detector
-
-Module for verifying whether an object has been garbage collected or not.
-
-Internally creates a weak reference to the object, and forces garbage collection to happen. If the reference is gone, it meant no one else was pointing to the object.
-
-## Example
-
-```javascript
-let reference = {};
-
-const detector = new LeakDetector(reference);
-
-// Reference is held in memory.
-console.log(detector.isLeaked()); // true
-
-// We destroy the only reference to the object.
-reference = null;
-
-// Reference is gone.
-console.log(detector.isLeaked()); // false
-```
