Someone needs to do a TypeScript compiler plugin to add multidimensional array slicing and operator overloading to the language, so these libraries can actually work the way PyTorch does.
I know operator overloading is controversial, but the way it allows automatic differentiation to work transparently through regular arithmetic expressions is very helpful. Without it these libraries will never feel like PyTorch.
JavaScript is so much faster than Python, and the package management experience is so much better, that I really think a JS library would have a chance to take market share from PyTorch in the long term if it had those features.
