不可变收藏品的真正优势是什么？ [英] What are the real advantages of immutable collections?

问题描述

Scala提供不可变的集合，例如 Set ，列表，地图。我明白不可变性在并发程序中有优势。然而，在常规数据处理中，不变性的优点是什么？

如果枚举子集，<$例如，c $ c>排列和组合

解决方案

什么是正常数据处理中的不变性的优点是：

一般来说，不可变对象更容易/更简单。 >

Scala provides immutable collections, such as Set, List, Map. I understand that the immutability has advantages in concurrent programs. However what are exactly the advantages of the immutability in regular data processing?

What if I enumerate subsets, permutations and combinations for example? Does the immutable collections have any advantage here?

解决方案

What are exactly the advantages of the immutability in regular data processing?

Generally speaking, immutable objects are easier/simpler to reason about.
