1.javascript & ECMAscript 就是js & es
ECMAscript 是js的标准，每年都会发布
2015之后发布前，ECMAscript 统称es6
2015之后发布后，ECMAscript 统称es5
2.javascript & jQuery
jQuery 就是个函数库
3.vue react
也是函数库（框架)（形式区分）
vue 构建一个vue体系

# QRCode.js
QRCode.js is javascript library for making QRCode. QRCode.js supports Cross-browser with HTML5 Canvas and table tag in DOM.
QRCode.js has no dependencies.
## Basic Usages
```
<div id="qrcode"></div>
<script type="text/javascript">
new QRCode(document.getElementById("qrcode"), "http://jindo.dev.naver.com/collie");
</script>
```
or with some options
```
<div id="qrcode"></div>
<script type="text/javascript">
var qrcode = new QRCode(document.getElementById("qrcode"), {
text: "http://jindo.dev.naver.com/collie",
width: 128,
height: 128,
colorDark : "#000000",
colorLight : "#ffffff",
correctLevel : QRCode.CorrectLevel.H
});
</script>
```
and you can use some methods
```
qrcode.clear(); // clear the code.
qrcode.makeCode("http://naver.com"); // make another code.
```
## Browser Compatibility
IE6~10, Chrome, Firefox, Safari, Opera, Mobile Safari, Android, Windows Mobile, ETC.
