命令式编程:命令“机器”如何去做事情(how),这样不管你想要的是什么(what),它都会按照你的命令实现。 声明式编程:告诉“机器”你想要的是什么(what),让机器想出如何去做(how)。 函数式编程 :和声明式编程是有所关联的,因为他们思想是一致的:即只关注做什么而不是怎么做。但函数式编程不仅仅局限于声明式编程。

注意:现代的编程语言很少是一种编程范式,大部分编程语言都是好几种编程范式混合而成,从而使编程语言本身更加易用。 编程范式代表语言声明式编程HTML、CSS、SQL。命令式编程(面向过程)C命令式编程(面向对象)C++、C#、Java、PHP、Python、Ruby、JavaScript。函数式编程Hask
Functional programming vs. imperative programmingThe functional programming paradigm was explicitly created to support a pure functional approach to problem solving. Functional programming is a form of declarative programming. In contrast, most mainstream languages, including object-oriented programming (OOP) ...

Begin by refactoring small, isolated pieces of your imperative code into a declarative style, leveraging libraries and frameworks that support this paradigm, like React for UI development or functional programming libraries in JavaScript. One common challenge is shifting your mindset from focusing on ste...
Declarative (functional). The declarative approach states what the final state should be. When run, the script or definition will initialize or configure the machine to have the finished state declared without defining how that final state should be achieved....
There are other common declarative abstractions for lists that are available in languages with a functional bent. For example, to add up all the items in a list imperatively we could do this: varnumbers=[1,2,3,4,5]vartotal=0for(vari=0;i<numbers.length;i++){total+=numbers[i]}console...
Purely functional code makes some things easier to understand: because values don't change, you can call functions and know that only their return value matters—they don't change anything outside themselves. But this makes many real-world applications difficult: how do you write to a database...
