C's and C++'s math functions in TypeScript & JavaScript

Assorted common math functions & utilities

Array#isArray for older browsers

Get the command from a shebang

Run a function exactly one time

Resolve the path of a module like `require.resolve()` but from a given path

JSON parse & stringify that supports binary via bops & base64

Callback wrapping utility

ECMAScript AST recursive visitor

deterministic `JSON.stringify()` - a faster version of substack's json-stable-strigify without jsonify

Allows users to use generators in order to write common functions that can be both sync or async.

deterministic JSON.stringify() with custom sorting to get deterministic hashes from stringified results, with no public domain dependencies

Light ECMAScript (JavaScript) Value Notation - human written, concise, typed, flexible

Fast (and loose) selective `process.env` replacer using js-tokens instead of an AST

process.nextTick but always with args

Safer Node.js Buffer API

Normalize slashes in a file path to be posix/unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes, unless disabled.

Buffers events from a stream until you are ready to handle them.

Pass two numbers, get a regex-compatible source string for matching ranges. Validated against more than 2.78 million test assertions.

Use node's fs.realpath, but fall back to the JS implementation if the native one fails
