I know that Chrome V8 Engine has some option that can be set like "command-line" flags using v8::V8::SetFlagsFromString(). But where can I find description of the each flag? I did not succeed with googling for this info so far. Does anyone know the place in documentation or some other resource that describes V8 flags?
You will get the actual list for your V8 version in a source file flag-definitions.h
As I remember, there is a --help flag in V8, that prints allowed flags and terminates. You can run node --v8-options to see the options for V8 version used in the Nodejs.
