Lazy.js is a functional utility library for JavaScript that provides lazy evaluation and immutable data structures. It offers a wide range of methods for working with arrays, objects, and sequences in a functional programming style. Lazy.js allows you to create sequences that are evaluated only when needed, improving performance by avoiding unnecessary computations.
Compared to other utility libraries like Lodash or Underscore, Lazy.js stands out for its lazy evaluation approach, which can be beneficial for handling large datasets efficiently. However, Lazy.js is no longer actively maintained and is considered a legacy library. It is recommended to explore alternative libraries like Lodash or Ramda for modern and actively supported functional programming utilities.
