引战 -- VUE.JS 是否真的无比强大?还是粉丝过于头脑发热?

其实很早想再写一篇文章,可惜没什么素材,今天写代码时候一个很小的CSS问题,问了3个技术群,居然没有一个人可以回答出来的,然后还是靠自己花了几分钟解决了,但也因为这么一个问题引发了一场争论,我个人觉得目前市面上VUE.JS的市场似乎有所增长,3年前我就在关注VUE.JS,不过当时开发系统时候,选择前端框架时候并不会深入去了解哪一款前端框架适合,我只知道,什么东西可以快速完成任务即可,毕竟对于客户而言,并不关心您用了什么技术实现,对于开发的语言或者框架来说,同样一套系统,也许A框架可以完成的话,B框架几乎也可以完成,只是所话费的时间多少而已。

web是如何实现跨域的

跨域是指从一个域名的网页去请求另一个域名的资源。比如从www.baidu.com 页面去请求 www.google.com 的资源。跨域的严格一点的定义是:只要 协议,域名,端口有任何一个的不同,就被当作是跨域 浏览器有同源策略本身是禁止跨域访问的 为什么浏览器要限制跨域访问呢?原因就是安全问题:如果一个网页可以随意地访问另外一个网站的资源,那么就有可能在客户完全不知情的情况下出现cookie泄露的安全问题 为什么要跨域: 既然有安全问题,那为什么又要跨域呢? 有时公司内部有多个不同的子域,比如一个是location.company.com ,而应用是放在app.company.com , 这时想从 app.company.com去访问 location.company.com 的资源就属于跨域

A programming paradigm is a fundamental style of computer programming. There are four main paradigms: imperative, declarative, functional (which is considered a subset of the declarative paradigm) and object-oriented. Declarative programming : is a programming paradigm that expresses the logic of a computation(What do) without describing its control flow(How do). Some well-known examples of declarative domain specific languages (DSLs) include CSS, regular expressions, and a subset of SQL (SELECT queries, for example) Many markup languages such as HTML, MXML, XAML, XSLT… are often declarative. The declarative programming try to blur the distinction between a program as a set of instructions and a program as an assertion about the desired answer. Imperative programming : is a programming paradigm that describes computation in terms of statements that change a program state. The declarative programs can be dually viewed as programming commands or mathematical assertions. Functional programming : is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in state. In a pure functional language, such as Haskell, all functions are without side effects, and state changes are only represented as functions that transform the state. ( 出处:维基百科)
