12 Functional Programming libraries and projects
8.3 5.6 L3 Javavʌvr (formerly called Javaslang) is a non-commercial, non-profit object-functional library that runs with Java 8+. It aims to reduce the lines of code and increase code quality.
7.9 0.7 L5 JavaBackport of Java 8's lambda expressions to Java 7, 6 and 5
6.8 0.2 L2 JavajOOλ - The Missing Parts in Java 8 jOOλ improves the JDK libraries in areas where the Expert Group's focus was elsewhere. It adds tuple support, function support, and a lot of additional functionality around sequential Streams. The JDK 8's main efforts (default methods, lambdas, and the Stream API) were focused around maintaining backwards compatibility and implementing a functional API for parallelism.
6.7 2.5 L3 JavaEnhancing Java Stream API
6.1 0.0 L3 JavaAn advanced, but easy to use, platform for writing functional applications in Java 8.
5.1 3.7 JavaFunctional patterns for Java
4.6 0.0 L4 JavaJava 8 annotation processor and framework for deriving algebraic data types constructors, pattern-matching, folds, optics and typeclasses.
4.4 0.0 L5 JavaStream utilities for Java 8
4.1 8.2 L1 Javajava port of Underscore.js
2.8 7.1 L5 JavaA library that simplifies error handling for Functional Programming in Java
2.7 -Functional extensions to Guava.
-Functional component library that provides persistent data types and functional control structures.
Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.
