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({
    /**
     * 頁面的初始數(shù)據(jù)
     */
    data: helloData,
    changeName: function (e) {
        this.setData({
            name: 'MINA'
        })
    }
})

開發(fā)者通過框架將邏輯層數(shù)據(jù)庫中的name與視圖層的name進(jìn)行了綁定，所以在頁面一打開的時(shí)候會(huì)顯示Hello WeChat 。

當(dāng)點(diǎn)擊按鈕的時(shí)候，視圖層會(huì)發(fā)送changeName的事件給邏輯層，邏輯層找到對應(yīng)的事件處理函數(shù)。

邏輯層執(zhí)行了setData的操作，將name從WeChat 變?yōu)?MINA，因?yàn)樵摂?shù)據(jù)和試圖層已經(jīng)綁定了，從而視圖層會(huì)自動(dòng)改變?yōu)镠ello MINA。

微信小程序不僅在底層架構(gòu)的運(yùn)行機(jī)制上做了大量的優(yōu)化，還在重功能（如page切換、tab切換、多媒體、網(wǎng)絡(luò)連接等）上使用接近于native的組件承載。所以微信小程序MINA有著接近原生App的運(yùn)行速度，做了大量的框架層面的優(yōu)化設(shè)計(jì)，對Android端和iOS端做了高度一致的呈現(xiàn)，并且準(zhǔn)備了完備的開發(fā)和調(diào)試工具。
