小程序是采用MINA框架

<!--demo.wxml-->
<view> Hello {{name}}</view>
<button bindtap="changeName">Click Me</button>

// demo.js
var helloData = {
    name: 'WeChat'
}

Page({
    /**
     * 页面的初始数据
     */
    data: helloData,
    changeName: function (e) {
        this.setData({
            name: 'MINA'
        })
    }
})

开发者通过框架将逻辑层数据库中的name与视图层的name进行了绑定，所以在页面一打开的时候会显示Hello WeChat 。

当点击按钮的时候，视图层会发送changeName的事件给逻辑层，逻辑层找到对应的事件处理函数。

逻辑层执行了setData的操作，将name从WeChat 变为 MINA，因为该数据和试图层已经绑定了，从而视图层会自动改变为Hello MINA。

微信小程序不仅在底层架构的运行机制上做了大量的优化，还在重功能（如page切换、tab切换、多媒体、网络连接等）上使用接近于native的组件承载。所以微信小程序MINA有着接近原生App的运行速度，做了大量的框架层面的优化设计，对Android端和iOS端做了高度一致的呈现，并且准备了完备的开发和调试工具。

小程序配置

全局配置app.json

进行pages配置String Array，window配置Object，tabBar配置Object，networkTimeout配置Object，debug配Boolean置。
