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.

A lean Promises and Async lib for ES6/ES7

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).

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

Basic operations on iterables

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.

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.

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.

An iterable is a sequence of values.

An array is a collection of values, stored contiguously.

Utilities for JavaScript Iterable and AsyncIterable

Rust-style iterator adapters for TypeScript, providing a rich set of functional operations for iterating over collections

A DOM-like interface for querying Javascript Objects

Query library for ECMAScript iterables.

A dependable promises and async utility belt

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

filters/finds, maps, reduces, and sorts

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

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

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

LINQ-like syntax using tagged templates.

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

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

Functionally - A utility belt for functional JavaScript

Javascript Iterable/Iterator/Generator-function utilities.

Recursively reduce an object to match a given map.

_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

kafka-streams for Node.js

Perform filter + map or map + filter operations on an array in one go

A functional query engine, that operates over streams of js objects, and can be optimized via database indexes.

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

asynchronous query language, for the usual functional list processing functions: map, select, reduce, but async-friendly

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.
