Script Preparation code:
let obj = {__proto__: null,a:3,*[Symbol.iterator](){yield this.a; yield this.a;}, method(){return ''}, get getter(){return this.a}, set setter(val){this.a=val}}
Tests:
Reflect
for(let i = 300; i--;) { Reflect.setPrototypeOf(obj, Reflect.getPrototypeOf(obj)) obj.method() obj.setter = obj.getter; [...obj] }
Object
for(let i = 300; i--;) { Object.setPrototypeOf(obj, Object.getPrototypeOf(obj)) obj.method() obj.setter = obj.getter; [...obj] }
__proto__
for(let i = 300; i--;) { obj.__proto__ = obj.__proto__ obj.method() obj.setter = obj.getter; [...obj] }
