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, filter, reduce, 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.
Compared to modern alternatives like Lodash, Underscore is considered a legacy library with limited updates and maintenance. While it still provides useful functionality, developers may prefer using Lodash for its improved performance, additional features, and active community support.
