Constant-time comparison of Buffers

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

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

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

Detect the archive type of a Buffer/Uint8Array

`util.inspect` with additional type information

A 2D spatial index for axis-aligned boxes

Turn any collection of objects into its own efficient tree or linked list using Symbol

Fast JavaScript array sorting by implementing Python's Timsort algorithm

Deep comparison of 2 instances for should.js

64-bit big-endian signed integer-to-string conversion

Like Promise.all, but save rejections until all promises are resolved

An arbitrary-precision Decimal type for JavaScript.

Returns true if any values exist, false if empty. Works for booleans, functions, numbers, strings, nulls, objects and arrays.

Zero CPU overhead, zero dependency, true event-loop blocking sleep
