### [Function.prototype.caller](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/caller)

显示函数的调用栈，即上层函数。  
fun.caller === arguments.callee.caller  
arguments.callee 代表的是正在执行的fun     
The **`caller`** accessor property of [`Function`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function) instances represents the function that invoked this function. For [strict](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode), arrow, async, and generator functions, accessing the `caller` property throws a [`TypeError`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypeError).
