举例说明Object.defineProperty会在什么情况下造成循环引用导致栈溢出？

var data = {    count: 1,    value: 2}Object.defineProperty(data, 'count', {    enumerable: true,    configurable: true,    get: function () {        console.log('你访问了count', this.count); // 循环读取data.count 导致报错        return this.value    },    set: function (newVal) {        console.log('你设置了count');    }})console.log(data.count) // 报错 Maximum call stack size exceeded
