Typescript utils function library for modern javascript

Most functional javascript object validation library

js utils library, includes function library、class library

Array#isArray for older browsers

Get the command from a shebang

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

Callback wrapping utility

Run a function exactly one time

JSON parse & stringify that supports binary via bops & base64

ECMAScript AST recursive visitor

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

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

process.nextTick but always with args

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

Safer Node.js Buffer API

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

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

type-check allows you to check the types of JavaScript values at runtime with a Haskell like type syntax.
