just - A library of dependency-free utilities that do just do one thing.

---

A library of zero-dependency npm modules that do just do one thing. A guilt-free alternative to those bulkier utility libraries. Ideal for mobile web development or wherever bytes are precious. We welcome contributions. Please follow our contribution guidelines.

streamjs - Lazy Object Streaming Pipeline for JavaScript

---

Stream.js is a lightweight (2.6 KB minified, gzipped), intensely tested (700+ assertions, 97% coverage) functional programming library for operating upon collections of in-memory data. It requires EcmaScript 5+, has built-in support for ES6 features and works in all current browsers, Node.js and Java 8 Nashorn. Before explaining how Stream.js works in detail, here's a few real world code samples.

typescript-collections - A generically typed set of collections for use with TypeScript

---

It is a complete, fully tested data structure library written in TypeScript. This project uses TypeScript Generics so you need TS 0.9 and above.

superstruct - A simple and composable way to validate data in Javascript.

---

A simple and composable way to validate data in JavaScript. Superstruct makes it easy to define interfaces and then validate JavaScript data against them. Its type annotation API was inspired by Typescript, Flow, Go, and GraphQL, giving it a familiar and easy to understand API.

101 - A modern JS utility library

---

Just like ES6's Object.assign. Extend an object with any number of objects (returns original). Functional version of &&. Works great with array.reduce.

numjs - Like NumPy, in JavaScript

---

Besides its obvious scientific uses, NumJs can also be used as an efficient multi-dimensional container of generic data. NumJs is licensed under the MIT license, enabling reuse with almost no restrictions.

MJExtension - A fast, convenient and nonintrusive conversion between JSON and model

---

A fast, convenient and nonintrusive conversion between JSON and model. Your model class don't need to extend another base class. You don't need to modify any model file.

ndarray - 📈 Multidimensional arrays for JavaScript

---

Modular multidimensional arrays for JavaScript.ndarrays can be transposed, flipped, sheared and sliced in constant time per operation. They are useful for representing images, audio, volume graphics, matrices, strings and much more. They work both in node.js and with browserify.

on-change - Watch an object or array for changes

---

It works recursively, so it will even detect if you modify a deep property like obj.a.b[0].c = true.Uses the Proxy API.

globby - User-friendly glob matching

---

Based on glob, but adds a bunch of useful features and a nicer API.Returns a Promise<Array> of matching paths.

bytebuffer

---

A fast and complete ByteBuffer implementation using either ArrayBuffers in the browser or node Buffers under node.js, generated from a single source tree through MetaScript. The library is compatible with CommonJS and AMD loaders and is exposed globally as dcodeIO.ByteBuffer if neither is available.

LArray - Large off-heap arrays for Java/Scala

---

A library for managing large off-heap arrays that can hold more than 2G (2^31) entries in Java and Scala. Notably LArray is disposable by calling LArray.free or you can let GC automatically release the memory. LArray also can be used to create an mmap (memory-mapped file) whose size is more than 2GB

faster

---

faster.js is a Babel plugin that compiles idiomatic Javascript to faster, micro-optimized Javascript. faster.js rewrites common Array method calls to faster code that does the same thing (usually - see When NOT to use faster.js). This results in performance boosts (especially on code that relies heavily on Array methods) while maintaining code readability, but comes at the cost of a slightly larger bundle size. If having a small Javascript bundle size is much more important for you than performance is, you should not use faster.js.

prelude-ls - prelude

---

is a functionally oriented utility library. It is powerful and flexible. Almost all of its functions are curried. It is written in, and is the recommended base library for, LiveScript. See the prelude.ls site for examples, a reference, and more.
