Scala is a statically typed programming language and compiler that combines object-oriented and functional programming paradigms. It serves as a cross-platform runtime language capable of targeting the Java Virtual Machine and JavaScript to share logic between backend servers and web frontends. The project provides a functional programming framework with immutable data structures and higher-order functions to build reliable concurrent and distributed applications. It distinguishes itself through deep interoperability with Java and JavaScript ecosystems and the ability to transform code into n

Clojure is a general-purpose, functional programming language hosted on the Java Virtual Machine. It is a homoiconic S-expression language that represents programs as nested data structures, allowing code to be manipulated and evaluated as data. The project provides a framework for JVM interoperability, enabling the invocation of Java methods and integration with other JVM-based languages. It distinguishes itself through a persistent data structure library that uses bitmapped vector tries to manage immutable collections and a programmatic REPL for interactive software development and real-tim

Scala 3 is an open-source, statically typed programming language that compiles to JVM bytecode, combining object-oriented and functional programming paradigms. Its core identity is defined by a sophisticated type system that includes traits, generics, union types, and a dependent object type system where types can depend on runtime values through path-dependent and singleton types. The language distinguishes itself through several advanced type-level and metaprogramming capabilities. It features a contextual abstraction mechanism using given instances and using clauses for compile-time implic

Groovy is a JVM programming language and metaprogramming framework that provides a Java compatible environment for building applications. It functions as a dynamic scripting language and a tool for authoring domain-specific languages, allowing for the execution of custom scripts and the creation of specialized mini-languages with concise syntax. The project is distinguished by its ability to modify program behavior and class definitions through both compile-time and runtime metaprogramming. It utilizes a hybrid typing model that combines dynamic method resolution with optional static type che

Aviatorscript is a high-performance scripting language and expression evaluation engine designed for integration within Java applications. It enables the dynamic execution of mathematical and logical formulas by compiling script instructions directly into Java bytecode at runtime. The engine distinguishes itself by transforming dynamic logic into machine-readable instructions, allowing for near-native execution speeds. It includes a built-in caching mechanism that stores compiled bytecode to eliminate redundant parsing and compilation overhead during repeated formula execution. This library

Rhino 是一个基于 Java 的 JavaScript 引擎，实现了用于在 Java 虚拟机（JVM）内执行的 ECMAScript 兼容层。它作为一个嵌入式脚本引擎和脚本桥接器，允许将 JavaScript 代码集成并执行在 Java 应用中。 该项目通过将 Java 类和对象映射到 JavaScript 环境中，促进了跨语言的直接通信。这种集成使脚本能够通过专用的映射机制与内部系统服务和原生宿主对象进行交互。 该引擎通过将 JavaScript 编译为 Java 字节码来优化性能，并支持双模式执行模型以平衡启动时间和运行时速度。它包括跨语言数据序列化、XML 处理以及为并发任务管理隔离执行上下文的功能。 提供了一个交互式 Shell，用于逻辑的实时编辑和调试。

JRuby 是一个运行在 Java 虚拟机（JVM）上的 Ruby 语言实现。它充当跨语言运行时和执行环境，允许 Ruby 代码在 JVM 上运行并与 Java 应用共享内存。 该项目充当 Ruby 和 Java 之间的桥梁，使 Ruby 脚本能够直接调用 Java 类和库。它还提供了一种将 Ruby 解释器嵌入到 Java 应用中以允许动态脚本编写的机制。 该运行时利用 JVM 实现系统可扩展性，并确保跨不同操作系统的一致执行环境。

Frege is a purely functional programming language that compiles to JVM bytecode, providing Haskell-like semantics for the Java platform. It is built around a Haskell-inspired compiler that implements non-strict evaluation and a static type inference system to ensure data immutability and prevent side effects. The project distinguishes itself through a sophisticated type system featuring rank polymorphism, type-class based dispatch, and static purity enforcement. It includes a JVM language bridge and a foreign function interface that map Java classes and interfaces into functional types, allow
