This file is part of Dev Tools implementation, which resides within Blink source tree: Source/core/inspector/InjectedScriptSource.js.
该文件是 Dev Tools 实现的一部分，它位于 Blink 源代码树中：Source/core/inspector/InjectedScriptSource.js.
There is Apple copyright because Blink itself is fork of WebKit, at that copyright is retained from there.

VMxyzidentifiers are generated by devtools themsevles for dynamically injected scripts that have no associated URL. See addScriptmethod in Source/devtools/front_end/bindings/DefaultScriptMapping.js
