Map Reduce

An ESnext spec-compliant iterator helpers shim/polyfill/replacement that works as far down as ES3.

Array methods for ES6 Iterators

Walk any kind of tree structure depth- or breadth-first. Supports promises and advanced map-reduce operations with a very small API.

Isomorphic map-reduce function to flatten an array into the supplied array

Small library to simplify working with Generators and Iterators in Javascript / Typescript

An inverted index that allows javascript objects to be easily serialised and retrieved using promises and map-reduce

Make array iteration easy when using async/await and Promises

Convenient and dependency free wrapper for working with arrays and objects.

ES6 Promise Shim

Component-wise operations on ndarrays

Require multiple modules using glob patterns. Supports exclusions.

Utilities for consuming, creating and manipulating node streams.

A library of async iterator extensions for JavaScript including ```map```, ```reduce```, ```filter```, ```flatMap```, ```pipe``` and [more](https://github.com/jamiemccrindle/axax/blob/master/docs/API.md#functions).

Basic operations on iterables

Map/Reduce promise like returned API -- Really not way to properly describe this module..

Async enabled each(), map(), filter() functions that work just like their standard counterparts, but can be used with async/await and also provide concurrency limiting. Includes built-in typings and JSDoc comments for IntelliSense documentation.

An array is a collection of values, stored contiguously.

Persistent Data Structures for JavaScript

Like underscore for Node streams. Map, reduce, filter, fork, pipeline and other utility functions for iterating over object mode streams.

An iterable is a sequence of values.

Functional operation helpers (underscore-like) for working with map, filter, reduce, etc

A simple and powerful async abstraction lib for easily writing Node.js code.

Query library for ECMAScript iterables.

filters/finds, maps, reduces, and sorts

Provides LINQ-like fluent api operations for iterables and async iterables (ES2018+).

A DOM-like interface for querying Javascript Objects

LINQ-like syntax using tagged templates.

Utilities for JavaScript Iterable and AsyncIterable

A dependable promises and async utility belt

async/await-ready array methods for JavaScript and Node.js

Array.map but for objects with good TypeScript support. A small and simple integration.

A collection of streams that work well with promises (through, map, reduce)

Allow perform every, filter, find, findIndex, forEach, map, reduce, reduceRight and some on array using Async callback

Reducers you can use for composing reducer hierarchy like with combineReducers from redux

kafka-streams for Node.js

_declarative-js_ is modern JavaScript library, that helps to: - tackle array transformation with built in JavaScript array api (e.g. `array.filter(toBe.unique())`), - provide a type-level solution for representing optional values instead of null referen

Functionally - A utility belt for functional JavaScript

Recursively reduce an object to match a given map.

Functional methods like forEach, map, filter, and other Array methods for Objects in javascript

Array-like methods for objects

A collection of streams that work well with promises (through, map, reduce). Think Through2 with promises

A familiar set of functions that operate on JavaScript iterables (ES2015+) in a similar way to .NET's LINQ does with enumerables.

async functional library
