Lodash is a fork of Underscore.js.

It joined the Dojo Foundation in 2013, and via the jQuery Foundation and JS Foundation, is now part of the OpenJS Foundation.

Summary
Lodash is a JavaScript library that helps programmers write more concise and maintainable JavaScript.

It can be broken down into several main areas:


 * Utilities: for simplifying common programming tasks such as determining type as well as simplifying math operations.
 * Function: simplifying binding, decorating, constraining, throttling, debouncing, currying, and changing the pointer.
 * String: conversion functions for performing basic string operations, such as trimming, converting to uppercase, camel case, etc.
 * Array: creating, splitting, combining, modifying, and compressing
 * Collection: iterating, sorting, filtering, splitting, and building
 * Object: accessing, extending, merging, defaults, and transforming
 * Seq: chaining, wrapping, filtering, and testing.

It has had multiple releases, so not all functions are available in all implementations. For example,  has only been available since version 3.0.0.
