Javascript 是函数式编程语言吗? [英] Is Javascript a Functional Programming Language?

问题描述

仅仅因为函数是一等对象，有闭包，还有高阶函数，Javascript就配得上函数式编程语言吗?我认为它缺少的主要内容是 Pure Functions，它感觉"不像其他函数式语言，如 lisp(尽管这并不是它不是函数式语言的真正原因......)

Just because functions are first class objects, there are closures, and higher order functions, does Javascript deserve to be called a Functional Programming language? The main thing I think it lacks is Pure Functions, and it doesn't 'feel' like other functional languages, like lisp (although thats not really a good reason for it not to be a functional langauge...)

推荐答案

重复 我自己对类似问题的回答，

没有公认的定义函数式编程语言.

There's no accepted definition of functional programming language.

如果你将函数式语言定义为支持一流的语言函数和 lambdas，然后是的，JavaScript *是 *函数式语言.

If you define functional language as the language that supports first class functions and lambdas, then yes, JavaScript *is* a functional language.

如果您还考虑以下因素支持不变性，代数数据类型，模式匹配，部分应用程序等然后不，JavaScript*不是*函数式语言.

If you also consider the factors like support for immutability, algebraic data types, pattern matching, partial application etc then no, JavaScript *is not* a functional language.
