如何在JavaScript代码中记录垃圾收集内容？ [英] How can I log what is being garbage collected in my javascript code?

问题描述

我已经构建了一个应用程序，浪费了40％的时间来收集垃圾，我正在努力找出它来自哪里。我在自己的代码中发现了任何可能的问题，但它仍然存在。我开始怀疑有些第三方代码是问题所在，我想知道是否可以以某种方式追踪垃圾收集的内容。如果有Chrome特定的答案，那就太好了，但我会在这一点上采取任何行动。

我会从以下开始：

• DevTools>个人资料


• 拍摄堆快照


• 使用应用程序


• 再次拍摄堆快照


• 在比较模式下检查第二张快照

I've built an application that wastes 40% of its time collecting garbage, and I'm at my wits' end trying to find out where it is coming from. I've corralled any possible problems in my own code, yet it persists. I'm beginning to suspect some third party code of being the problem, and I'd like to know if I can somehow track down what is being garbage collected. If there's a Chrome-specific answer, that'd be great, but I'll take anything at this point.

解决方案

In Chrome I would start with following:

• DevTools > Profile
• Take Heap Snapshot
• Working with the application
• Take Heap Snapshot again
• Inspect the second snapshot in the comparision mode
