Eclipse Collections, Java Streams & Vavr - What's in them for Functional Programming
Intuitive collections types can certainly help developers positively in terms of increased developer productivity and higher readability. As a developer on JVM you have plenty of options from the community. In this presentation, I compare three popular collections libraries - Eclipse Collections, Java Streams API, and Vavr. I present the code examples using all the three APIs. I firmly believe, there is no one library that is perfect for all situations. Hence we compare these libraries along the dimensions of mutability/ immutability, eager/lazy evaluation, richness of expression, error handling aspects. By the end of the presentation, we identify the strong areas for each of these APIs.
