numpy-ts

numpy-ts is a TypeScript/JavaScript library that ports 94% of the NumPy API (476 of 507 functions) to the JS ecosystem. It is fully type-safe, tree-shakeable, has zero dependencies, and runs in Node.js, Bun, Deno, and browsers. Over 6,000 tests validate outputs directly against NumPy, covering arithmetic, FFT, linear algebra, random distributions, and more. A migration guide helps Python/NumPy users translate code directly.
