Lodash is a JavaScript library which provides utility functions for common programming tasks using the functional programming paradigm.
History
Lodash is a fork of Underscore.js.
It joined the Dojo Foundation in 2013,3 and via the jQuery Foundation and JS Foundation, is now part of the OpenJS Foundation.4
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, _.chunk has only been available since version 3.0.0.
