`download` HTML5

此属性指示浏览器下载URL而不是导航到URL，因此将提示用户将其保存为本地文件。

如果属性有一个值，它将在保存提示中用作预先填写的文件名 (用户仍然可以根据需要更改文件名)。
对允许的值没有限制，但是/和\被转换为下划线。
大多数文件系统限制文件名中的一些标点符号，浏览器会相应地调整建议的名称。

注意:

1. 此属性仅适用于同源 URLs。
2. 可以使用 blob: URLs 和 data: URLs 以方便用户下载 JavaScript 方式生成的内容（例如使用在线绘图的Web应用创建的照片）。
3. 如果HTTP头的Content-Disposition：存在，并且赋予了一个和这个属性不同的文件名，HTTP头优先于此属性。
4. 如果这个属性存在 Content-Disposition 被设置为 inline，火狐优先 Content-Disposition，像之前文件名的情况下，而Chrome则优先 download 属性。

Object

https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Object/prototype

Object.prototype 属性表示 Object 的原型对象。

JavaScript中几乎所有的对象都是 Object 的实例;

https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperties

Object.defineProperties() 方法直接在一个对象上定义新的属性或修改现有属性，并返回该对象。

https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty

Object.defineProperty() 方法会直接在一个对象上定义一个新属性，或者修改一个对象的现有属性，并返回这个对象。

https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Object/assign

Object.assign() 方法用于将所有可枚举的属性的值从一个或多个源对象复制到目标对象。并返回目标对象。

https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Object/create

Object.create() 方法使用指定的原型对象和其属性创建了一个新的对象。

深度拷贝问题

https://gist.github.com/xgqfrms-GitHub/61b92cd14761e71d9922cb182550ba11

https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Object/assign

针对深度拷贝，需要使用其他方法 JSON.parse(JSON.stringify(obj));，因为 Object.assign() 拷贝的是属性值。
假如源对象的属性值是一个指向对象的引用，它也只拷贝那个引用值。

function test() {
  let a = { b: {c:4} , d: { e: {f:1}} };

  let g = Object.assign({},a);

  let h = JSON.parse(JSON.stringify(a));

  console.log(g.d); // { e: { f: 1 } }
  g.d.e = 32;

  console.log('g.d.e set to 32.') 
// g.d.e set to 32.
  console.log(g); // { b: { c: 4 }, d: { e: 32 } }
  console.log(a); // { b: { c: 4 }, d: { e: 32 } }

  console.log(h); 
// { b: { c: 4 }, d: { e: { f: 1 } } }


  h.d.e = 54;
  console.log('h.d.e set to 54.') ;
// h.d.e set to 54.

  console.log(g); // { b: { c: 4 }, d: { e: 32 } }
  console.log(a); // { b: { c: 4 }, d: { e: 32 } }

  console.log(h); 
// { b: { c: 4 }, d: { e: 54 } }
}
test();
