Benchmark: Object.create mutation vs Object.create mutation descriptors vs setPrototypeOf rm

Script Preparation code:

for (i = 0; i < 10; i++) {}

Tests:

Object.create mutation
const proto = { m1() { return 4324 }, m2() { return "park"} }; const obj = Object.create(proto) obj.age = 65 obj.name = "john"
Object.create mutation descriptors
const proto = { m1() { return 4324 }, m2() { return "park"} }; const obj = Object.create(proto, Object.getOwnPropertyDescriptors({age: 65, name: "john"}));
setPrototypeOf
const proto = { m1() { return 4324 }, m2() { return "park"} }; const obj = {age: 65, name: "john"} Object.setPrototypeOf(obj, proto);
