They provide some tools that imperative languages usually don't.
它们提供了命令式语言通常不提供的一些工具。
Users of imperative languages rely on assignments more than any other programming technique.
命令式编程的用户对赋值的依赖要超过其他编程技术。
In imperative languages, any method that can possibly return different values, given the same input, has side effects.
在命令式语言中，输入相同而可能返回不同值的方法，都有副作用。
Functions form the building blocks for processing and are imbued with several features not found in traditional imperative languages.
函数为流程构建了功能模块，并具有传统命令式语言中所不具有的一些功能。
Functional programming gives you new, different building blocks to achieve the same goals that imperative languages accomplish with other mechanisms.
函数式编程为您提供了新的、不同的构建块，可以实现命令式语言使用其他机制实现的相同效果。
It's interesting to note that recursion is as efficient as iteration in imperative languages because the recursion is translated into iteration under the covers.
有趣的是要注意递归与迭代在命令性语言中同样高效，因为递归在幕后被转化成迭代。
The functional programming approach is easy to understand, but can be difficult to apply if you are used to the more procedural and state-focused imperative languages.
函数编程方式很容易理解，但是如果您习惯了过程序和关注状态的命令式语言，可能不太容易适应它。
XYZ/E is a temporal logic system as well as a programming language. It can represent almost every kind of significant features in conventional imperative languages.
既是一个时序逻辑系统也是一个程序设计语言，它能表示普通高级语言中几乎所有的重要机制。
Recursion is important to Haskell because unlike imperative languages, you do computations in Haskell by declaring what something is instead of declaring how you get it.
递归在haskell中至关重要。与命令式语言要求你去表达求解的方式不同，haskell更倾向于让你提供问题的描述。
Programmers of imperative languages will be surprised by what you can do without flow control; they'll be even more surprised at how much easier many tasks are without it!
命令式语言程序员将对不使用流程控制就可以完成的工作而感到惊讶；如果不使用它，很多工作会更加简单，这将使他们更为惊讶！
Imperative programming is often a more natural and intuitive starting place for new programmers which is why most programming introductions focus on imperative languages and methods.
对新程序员来说，命令式程序设计通常是一个更为自然和直观的起点，这就是为什么大部分程序设计说明都集中关注命令式语言和方法的原因。
It's hard to imagine programming languages without these characteristics because imperative languages' "tell me how to do it" approach is so firmly entrenched in our everyday programming philosophies.
很难想像没有这些特征的编程语言，因为命令式语言“告诉我如何做”的方式是如此深刻地确立在我们的日常编程哲学中。
