Yeah i meant ArrayBuffer*Builder*::Append my bad.... but when it is actually called in blink ? Cause by the name it has to do with Arraybuffers.. Plus if i build v8 so i can examine the memory layout, where is the code on how v8 handeles arraybuffer ? Where is the doc or some source where there's explained how v8 represents object in memory, how can i be sure that in memory i'm not starrying at a pointer instead of an object or something like that...
