附加语法糖：关于克隆对象的速度研究。

+ +

https://dassur.ma/things/deep-copy/ 

+ +

博客作者认为目前（参考）最快的object克隆、复制方式。

+ +
function structuralClone(obj) {
+  return new Notification('', {data: obj, silent: true}).data;
+}
+ +

Syntax 表达式

+ +
var data = Notification.data;
+
+ +

Value（返回值）

+ +

结构化的克隆数据

+ +

Examples 例子

+ +

产生一个 notification; 简单的options 作为构造参数, 将会触发以option为构造参数的 Notification() .

+ +
var options = {
+  body: 'Do you like my body?',
+  data: 'I like peas.'
+}
+
+var n = new Notification('Test notification',options);
+
+n.data // should return 'I like peas.'
