 2  
 3  Module for verifying whether an object has been garbage collected or not.
 4  
 5  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.

 7  ## Example
 8  
 9  ```javascript
10  (async function () {
11    let reference = {};
12    let isLeaking;
13  
14    const detector = new LeakDetector(reference);
15  
16    // Reference is held in memory.
17    isLeaking = await detector.isLeaking();
18    console.log(isLeaking); // true
19  
20    // We destroy the only reference to the object.
21    reference = null;
22  
23    // Reference is gone.
24    isLeaking = await detector.isLeaking();
25    console.log(isLeaking); // false
26  })();
27  ```
