What are some real-world applications of functional libraries?

Functional libraries are widely used in various domains, such as data processing, web development, and machine learning. For example, libraries like Lodash and Ramda in JavaScript help with data manipulation and functional programming techniques.

Can you give me an example of how Lodash is used in a project?

Sure! In a web application, Lodash can be used to simplify tasks like filtering an array of user objects based on certain criteria, or deep cloning an object to avoid mutation.

What about in Python? Are there functional libraries there?

Yes, Python has libraries like functools and toolz that provide functional programming tools. They can be used for operations like memoization, currying, and composing functions.

How do these libraries improve code quality?

Functional libraries promote immutability and pure functions, which can lead to more predictable and easier-to-test code, ultimately improving maintainability.
