Concrete methods
Returns an integer representing a "version tag" derived from the V8 version, command line flags and detected CPU features. This is useful for determining whether a vm.Script cachedData buffer is compatible with this instance of V8.

Uses a DefaultDeserializer with default options to read a JS value from a buffer.

Generates a snapshot of the current V8 heap and returns a Readable Stream that may be used to read the JSON serialized representation. This conversation was marked as resolved by joyeecheung This JSON stream format is intended to be used with tools such as Chrome DevTools. The JSON schema is undocumented and specific to the V8 engine, and may change from one version of V8 to the next.
