Typelead is the organization behind the development of Eta, a programming language that is a dialect of Haskell designed to run on the Java Virtual Machine (JVM). Eta aims to provide functional programming capabilities with strong type safety to the JVM ecosystem, allowing developers to leverage Haskell's concise and expressive syntax alongside the extensive libraries and tools available in the Java environment. The Eta language enables seamless interoperation with Java, making it a suitable choice for developers looking to integrate Haskell-like features into existing Java applications.
