规范里用来声明 var/let 变量的内部方法是 CreateMutableBinding()，初始化变量用 InitializeBinding()，为变量赋值用 SetMutableBinding()，
引用一个变量用 GetBindingValue()。在执行完 CreateMutableBinding() 后没有执行 InitializeBinding() 就执行 SetMutableBinding() 或者 
GetBindingValue() 是会报错的，这种表现有个专门的术语（非规范术语）叫 TDZ（Temporal Dead Zone）。

标准说用let和const初始化失败的变量将会永久的不能初始化了。

let/const v = xx // xx is not defined
let/const v = 1  // v has already been declared
v = 1; let c = v // v is not defined
