给博主补充一下，关于__proto__属性，
在浏览器环境下虽有这个实现，但非JS语言标准，
(试了下在Nodejs下也是有这个属性的)
function fnc(){}
console.log('prototype: ', fnc.prototype)
console.log('__proto__:', fnc.__proto__)prototype: fnc {}
__proto__: [Function]
不过标准的用法应该是：Object.getPrototypeOf(fnc)
而不是直接访问__proto__属性
let obj = {}
obj.__proto__ === Object.getPrototypeOf(obj) // truefrom goodblog.
