A powerful programming language to build concurrent & distributed systems on the JVM.Getting Started
Eta is a pure, lazy, strongly typed functional programming language on the JVM. It brings two big ecosystems, the JVM and Haskell, together. This allows you to harness the best of both ecosystems to build your applications quickly and effectively. Eta's concurrency support helps you to build highly scalable systems.
Eta has a strongly-typed Foreign Function Interface (FFI) that allows you to safely interoperate with Java.
Eta has global type inference, giving you a dynamic language experience, but with a strong typing hidden underneath.
Eta offers a wide range of strategies for handling concurrency including Software Transaction Memory (STM), MVars, and Fibers.
