Thanks for all the advice, I know it is well-intended, but unfortunately this late in the project there is nothing that could change my mind anyway. It's too late.

But even if I had to start from scratch, I would still use C++. It is the most-used language in this field for rational reasons, not just for mistaken beliefs. Multi-threading is important, supporting custom pen tablets hardware is important, accessing Metal and Direct3D graphics API is important, being able to use the core as a shared library for command-line tools is important, being able to not crash when another tab makes the browser crash is important (okay, for this I could use electron). Being able to embed a Python interpreter is important (yes, it has to be Python it's a design decision). And we're not talking 1Ks vertices, but millions.

Again, AAA games are not developed in Javascript for a reason. Professional productivity graphics application have the same requirements than AAA games.

Tablets are important, so native apps for tablets makes sense if you think this is the main device people will use. ProCreate, Autodesk Sketchbook, etc. live on the tablet and native makes sense for that experience.

But then do not target desktop. You should target tablets and the pen-based interface on them.

I will also target iPads and Android tablets as native apps, yes. But most professional users use a powerful desktop computer with a Wacom Intuos or Cintiq. Some professional work requires hundreds of layers, and in the context of animation, you're not going to make the next Studio Ghibli animation on an iPad. You need your 64GBs or RAM.
