Lodash is a JavaScript library which provides utility functions for common programming tasks using the functional programming paradigm.


See also Underscore § 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]


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.
