😮 numpy-ts: A NumPy Implementation for TypeScript NumPy is a fundamental piece of the Python scientific computing ecosystem
😮 numpy-ts: A NumPy Implementation for TypeScript NumPy is a fundamental piece of the Python scientific computing ecosystem and well-entrenched in many use cases. JavaScript has some options in this regard (e.g. TensorFlow.js), but numpy-ts is an attempt to replace the NumPy experience as closely as possible (currently at 94% API coverage). There’s an online playground if you want to give it a quick spin. Nicolas Dupont
