Okay I will but, how could I be sure when blink on the renderer process executes arraybufferbuilder ?? Or one more thing, can u redirect me to checkout how v8 represents data in memory, how would it handle arraybuffers? The only thing I’ve managed to find ( in the github repo ) was a JavaScript file which contained if I remember correctly, 2 definitions of sorting algorithms.
