捷径探测器

用于验证对象是否已被收集到垃圾的模块 .

内部产生对对象的微弱引用,并迫使垃圾收集发生. 如果提法被删除,这意味着没有人指向物体.

示例

(async function () {
  let reference = {};
  let isLeaking;

  const detector = new LeakDetector(reference, {
    shouldGenerateV8HeapSnapshot: true,
  });

  // Reference is held in memory.
  isLeaking = await detector.isLeaking();
  console.log(isLeaking); // true

  // We destroy the only reference to the object.
  reference = null;

  // Reference is gone.
  isLeaking = await detector.isLeaking();
  console.log(isLeaking); // false
})();
