Underscore is a utility library for JavaScript that provides a wide range of functions to manipulate arrays, objects, functions, and other data types. It offers a functional programming style with functions like map, reduce, filter, and more, making it easier to work with data in a concise and efficient manner. Underscore also includes utility functions for common tasks like object iteration, type checking, and function binding.
While Underscore has been a popular choice for many developers, it is considered a legacy library with development now focused on its successor, Lodash. Lodash offers similar functionality with additional features, improved performance, and better modularity. It is recommended to migrate from Underscore to Lodash for ongoing support and enhancements.
