That isn’t my question.... Arraybufferbuilder:append how could I get that to be called. What I really need is a little guidance on how to understand how v8 will parse my JavaScript script and how it will allocate the data. Maybe even how a buffer or if there’s something that describes how buffers are handeled or if there’s a file or code that tells me that not the memory I know... just how it will execute it that’s all
