stdlib is a standard library for JavaScript and TypeScript with an emphasis on numerical and scientific computing, providing math, statistics, probability distributions, PRNGs, plotting, and general utilities. It runs in browsers and Node.js, is fully decomposable into individual packages, and includes a REPL, benchmark framework, and extensive documentation.

Use cases

• compute statistics and math functions in JavaScript
• evaluate probability distributions and PDFs/CDFs in Node.js
• generate random numbers with seedable PRNGs
• plot data for exploratory analysis in the browser
• validate and transform data with assertion utilities
• do scientific computing on the web
• find a JavaScript equivalent to NumPy or R's stats functions

When to choose

• you need rigorous, well-tested numerical or statistical routines in JS/TS
• you want a batteries-included standard library for Node.js or browsers
• you need seedable PRNGs or many probability distributions
• you want to bundle scientific computing into a web app

When to avoid

• you need GPU-accelerated or massively parallel numerical computing
• your project is in Python, R, or another language with mature scientific stacks
• you only need one small utility and want a minimal dependency
