js --print-bytecode # 执行以下命令,输出9 ./d8 ./test.js 内部方法的使用 还可以使用 V8 所提供的一些内部方法,只需要在启动 V8 时传入--allow-natives-syntax命令,你就可以在 test.js 中使用诸如HasFastProperties(检查一个对象是否拥有快属性)的内部方法(索引属性、常规属性、快属性等下文会介绍)。
By the way, the stack trace indicates that the process is running out of memory because it can't concatenate two (presumably large) strings. You might have just been lucky and skimmed the edge with older versions. I'm also running into something quite similar in our production instance since...

I have also produced crashes with following stack trace, using a similar test case, but it doesn't repro cleanly: FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory 1: 0x1042458d8 node::Abort() [/Users/keunwoo/h/node/env-16.17.0/bin/node] 2: 0x104245...
堆栈跟踪相关的调试可以使用console.trace。这个同样可以通过UI界面完成。当代码被打断点后,可以在Call Stack面板中查看相关堆栈信息。 上面介绍的都是挂在window.console这个对象下面的方法,统称为Console API,接下来的这些方法确切地说应该叫命令,是Chrome内置提供,在控制台中使用的,他们统称为Command Line API。
