Because it is one of the most popular and accessible programming languages. It can act as a gateway language for the millions of devs out there to try out NN's without the barrier of learning another language. Here are some other neural networks in JS: https://github.com/harthur/brain https://github.com/harthur/brain: Neural Networks in JS https://github.com/stevenmiller888/mind https://github.com/stevenmiller888/mind: a flexible neural network library https://github.com/cazala/synaptic https://github.com/cazala/synaptic: an architecture-free neural network library for node.js and the browser Sllightly off topic, but the Machine Learning department of the University of Tokyo has built a whole set of libraries for machine learning in Javascript: http://mil-tokyo.github.io/miljs.html http://mil-tokyo.github.io/miljs.html
