# numpy-ts NumPy implementation in TypeScript/JS. Source: [Console review]() Website: [https://numpyts.dev/]() Profile updated: 2026-10-16 Category: [Machine learning]() ## Supported tech stack Research checked: 2026-10-11 ### Runs on - Bun (Runtime) - Deno (Runtime) - WebAssembly (Runtime) ### Integrates with - JavaScript (Language) - TypeScript (Language) ### Written in - TypeScript (Language) Source: [Research source]() Documented compatibility; coverage may be incomplete. Written in describes implementation, not user-project language support. Numerical library implements NumPy-like APIs in TypeScript/JavaScript and WebAssembly; installation supports Bun and Deno. ## Console’s review — 2026-03-05 Reviewed: 2026-03-05 Author: [David Mytton]() Citation: [This review]() ### What we like Avoid splitting your stack if you’re already building in TS/JS. Tree-shakable library with universal runtime support across server and client. No additional dependencies. Validated against NumPy tests. ### Tradeoffs Not quite at 100% NumPY API coverage yet (94%). Slower than NumPy (average 11x slower, median 3x slower) for many of the benchmarks, as you’d expect. This review reflects Console’s assessment at publication on 2026-03-05. Features and limitations may have changed since the review date. ## Is numpy-ts a fit? Based on [Console’s review published on 2026-03-05](). Summary updated: 2026-10-16 ### Who it’s for Developers using TypeScript or JavaScript should consider this tool for numerical computations ### Why consider it It provides a tree-shakable library with universal runtime support ### Keep in mind It is slower than NumPy for many benchmarks [Selection criteria]() · [About Console]() · [Browse tools]()
