react源碼解析

A declarative, efficient, and flexible JavaScript library for building user interfaces.

declarative：聲明式。React將此做爲第一個詞，可見其重要性。declarative對應imperative（命令式），移步這裏看看什麼是 declarative Javascript.

對於react，declarative的含義是：declarative UI.

Declarative views make your code more predictable, simpler to understand, and easier to debug.

這說的是JSX語法，可以在JS裏面直接寫html和css，是一次大膽的創新。JSX讓人寫前端代碼寫得直呼過癮。

React is flexible and can be used in a variety of projects. You can create new apps with it, but you can also gradually introduce it into an existing codebase without doing a rewrite.

你沒有必要非在整個網頁或者整個項目中使用react。你能夠只在一個dom節點中使用，而後慢慢地去作重構。因此，使用react和使用jquery,angular並不衝突。
