I would guess that it is very unsuitable, since for anything but the most trivial models, even those &#x27;Python&#x27; libraries resort to highly-optimized (compiled) C subroutines, especially for the training part. Even then you require a highly nontrivial amount of time to train the network, especially if you are working with medium to large datasets.<p>Later on, when the speed is not so critical, you can do inference with those pretrained weights and your model implemented in Javascript.
