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 developers to create efficient data processing pipelines by chaining operations and delaying execution until necessary.
Lodash is a popular utility library for JavaScript that provides a wide range of functions for simplifying common programming tasks. It offers efficient and optimized functions for array manipulation, object manipulation, string manipulation, and more. Lodash is known for its consistency, performance, and ease of use, making it a go-to choice for many developers.

Popularity
Lodash is one of the most popular utility libraries for JavaScript. It has a large community following and is widely used in many projects. Lazy.js, while not as widely known, has its own dedicated user base and is popular among developers who prefer lazy evaluation and functional programming.
Size
Lodash is a comprehensive utility library with a large number of functions, which makes it a bit larger in size. Lazy.js, on the other hand, is focused on lazy evaluation and provides a lightweight implementation with a smaller codebase.
Functionality
Lodash offers a vast range of utility functions that cover a wide variety of use cases, including array manipulation, object manipulation, string manipulation, and more. It provides a consistent and easy-to-use API. Lazy.js, on the other hand, specializes in lazy evaluation, providing functions for lazy collection manipulation. It allows for efficient processing of large datasets and promotes functional programming paradigms.
Performance
Lodash is known for its optimized and highly performant functions. It has been battle-tested and optimized for performance across various JavaScript engines. Lazy.js, on the other hand, excels in scenarios where lazy evaluation can lead to significant performance improvements, especially when dealing with large datasets. However, for general use cases, Lodash is usually faster due to its mature and optimized implementation.
Developer Experience
Both Lodash and Lazy.js provide a great developer experience with well-documented APIs and comprehensive guides. Lodash has a larger community and more extensive documentation, making it easier to find examples and support. Lazy.js has a smaller community, but its documentation is still of good quality and provides examples for getting started.
Maintenance
Lodash is actively maintained and receives regular updates. It has a large community of contributors who help ensure its stability and reliability. Lazy.js, however, has seen fewer updates in recent years and may have a smaller maintenance community. It is worth considering the long-term maintenance implications when choosing between the two libraries.
