Considering that my experience with js has been like library books about web 1.0 -> doing unrelated stuff with computer graphics for most of my adult life -> holy moly you can do graphics in the browser I maybe need to trust that computers/browsers are fast now
With the material generation stuff seeing how three.js combines and processes big strings to make glsl shaders I'm like is this allowed?? But I wouldnt question manipulating like, kbs of data in anything other than JavaScript🤷♀️
