React极简教程: Hello,World!React简史React安装Hello,World

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)

WEB前端新人,怎么样构建自己的“前端技术体系”?用以在面试中打败其它竞争者

毫无疑问,对于现在的前端新人来讲,尤其是培训班出身的前端新人,找工作就是一场战争。目标就是那几个工作岗位,周围的人全是敌人,没什么同伴。而在昨天的。。。文章中,我已经说的很清楚,前端新人的核心竞争力,就是看谁更早的拥有自己的“前端技术体系。” 都是零基础,都是在培训班中学习,也许对于前端开发的全部理解与认识,都来自于培训班中老师的讲解,这时许多培训班出身的同学,他们的技术水平上限, 就是他们的培训老师的水平上限。---这也是许多公司不愿意要培训班学生的原因之一,技术上限太低。 首先建立第一条技能线,就是前
