A simple math and computer algebra system library
Do math on arrays: find divisors or factors of a number, sum or multiply an array, and much more!
Array#isArray for older browsers
Get the command from a shebang
JSON parse & stringify that supports binary via bops & base64
Callback wrapping utility
CLI arguments parser. Native port of python's argparse.
Run a function exactly one time
ECMAScript AST recursive visitor
Resolve the path of a module like `require.resolve()` but from a given path
Allows users to use generators in order to write common functions that can be both sync or async.
deterministic `JSON.stringify()` - a faster version of substack's json-stable-strigify without jsonify
Light ECMAScript (JavaScript) Value Notation - human written, concise, typed, flexible
process.nextTick but always with args
deterministic JSON.stringify() with custom sorting to get deterministic hashes from stringified results, with no public domain dependencies
Buffers events from a stream until you are ready to handle them.
Use node's fs.realpath, but fall back to the JS implementation if the native one fails
Create a stream that emits events from multiple other streams
Returns true if a string has an extglob.
The Node.js `util.deprecate()` function with browser support
type-check allows you to check the types of JavaScript values at runtime with a Haskell like type syntax.
Safer Node.js Buffer API
A small polyfill for Object.setprototypeof
Fast (and loose) selective `process.env` replacer using js-tokens instead of an AST
