Journal of Functional Programming

Journal of Functional Programming (commonly abbreviated as J. Funct. Program.) is the only journal devoted solely to the design, implementation and application of functional programming languages. Launched in 1991, it is now diamond open access, with a 2025 impact factor of 1.0.Journal of Functional Programming（常用缩写 J. Funct. Program.）是唯一专注于函数式程序设计语言的设计、实现与应用的期刊，1991 年创刊，现为钻石开放获取，2025 年影响因子为 1.0。^[1]

Scope

• Scope: anything related to functional programming is of interest, spanning the range from mathematical theory to industrial practice.学科定位： 期刊覆盖函数式程序设计从数学理论到工业实践的全部内容，凡与函数式程序设计相关者皆在兴趣之列。
• Subject coverage: directions include foundations such as semantics, abstract interpretation, lambda calculi, rewriting, logic, type theory and category theory, implementation aspects like compilation, architectures, parallelism, garbage collection, I/O, debugging and profiling, language design, and applications with programming techniques.收录主题： 具体方向包括基础理论（语义、抽象解释、lambda 演算、重写、逻辑、类型论、范畴论）、实现（编译、体系结构、并行、垃圾回收、输入输出、调试、剖析）、语言设计以及应用与编程技术。
• Article types: regular papers form the main diet, with dedicated tracks for tools and applications, commercial uses, education, tutorials, functional pearls, theoretical pearls, book reviews and special issues.体裁： 常规论文为主干，另设工具与应用、商业应用、教育、教程、函数式珍珠、理论珍珠、书评与专号等栏目。
