The stdlib project provides a numerical library for JavaScript and TypeScript applications.
About stdlib
stdlib is an open-source standard library for numerical and scientific computation, written in JavaScript and C for execution in browsers and Node.js. It covers mathematics, statistics, data processing, streams and general utilities, with a fully decomposable architecture that lets developers swap out or mix individual APIs rather than adopting the whole library.
The repository hosts the source code and documentation. Pricing information is not stated in the source, and installation instructions default to npm, though other package managers can be used by substituting their commands. Native add-ons interface with BLAS libraries and include pure JavaScript fallbacks. The source does not state geographic restrictions or usage limits.
