Scala 整体的语言表达力犀利,虽然有瑕疵,但足够体验到 FP 的神奇之处。当你深刻理解 Functor、Applicative、Monad,并落地在应用中,你会看到一个完全不同的世界。在这个世界中,不止是表面上的酷炫——所有的规... (展开) 我要写书评 Functional Programming in Scala的书评 ··· ( 全部4 条 ) 热门 只...
Recursion plays a larger role in pure functional programming than in imperative programming, in part because of the restriction that variables are immutable. Tail Calls and Tail-Call Optimization def factorial(i: BigInt): BigInt = { def fact(i: BigInt, accumulator: BigInt): BigInt = i matc...

The ability of Scala.Rx to gracefully handle the corresponding Rxs within Rxs allows it to gracefully fit into this paradigm, something I found lacking in most of the Related Work I surveyed.Most of the examples here are taken from the unit tests, which provide more examples on guidance on ...
Scalaz is a Scala library for functional programming. It provides purely functional data structures to complement those from the Scala standard library. It defines a set of foundational type classes (e.g.Functor,Monad) and corresponding instances for a large number of data structures. ...
functional programming in scala, second edition Scala is a powerful programming language that combines the functional and object-oriented programming paradigms. In the second edition of "Functional Programming in Scala," authors Paul Chiusano and Rúnar Bjarnason delve into the intricate details of ...
所以ExecutorService允许我们提交一个Callable值(在Scala中,我们可能只需使用一个lazy参数来提交),并返回一个相应的Future,该Future是一个计算的句柄,有可能在单独的线程中运行。我们可以使用Future的get方法获取一个值(该方法会阻塞当前线程,直到值可用为止),它还有一些额外功能可以用于取消(阻塞一定时间后抛出异常等)。
如果你需要在Scala中生成(伪)随机数,标准库中有一个名为scala.util.Random的类(https://mng.bz/7W8g),它拥有一个非常典型的命令式API,需要依赖副作用。下面展示了它的一个使用示例。Listing 6.1 Using scala.util.Random to generate random numbers
