### 1. `Symbol` 类的实例与 `typeof`
```javascript
const s = Symbol()
console.log(s === Object(s), typeof Object(s))
```
执行结果：
```javascript
// Node 10.13
false "object"

// Node 0.10 + babel-runtime@6.26.0
true "symbol"
```

*补充：这一差距是无法实现的，参见 http://www.ecma-international.org/ecma-262/#sec-object-constructor ，Object 转换的过程没有调用非内部方法*
