Benchmark: Object.create() vs literal destructure

Script Preparation code:

var emptyPair = {
  pair: '',
  svc: '',
  rate: 0,
  rateId: '',
  limit: 0,
  min: 0,
  minerFee: 0,
  unavailable: true,
  details: '',
  maxLimit: 0,
  chainPair: '',
}

var emptyPairNullProto = Object.create(null)
emptyPairNullProto.pair = ''
emptyPairNullProto.svc = ''
emptyPairNullProto.rate = 0
emptyPairNullProto.rateId = ''
emptyPairNullProto.limit = 0
emptyPairNullProto.min = 0
emptyPairNullProto.minerFee = 0
emptyPairNullProto.unavailable = true
emptyPairNullProto.details = ''
emptyPairNullProto.maxLimit = 0
emptyPairNullProto.chainPair = ''

Tests:

Object.create()
const a = Object.create(emptyPair, { details: { value: 'new details'}, pair: {value: 'from_to'} })
Destructure
const b = { ...emptyPair, details: 'new details', pair: 'from_to', }
Object.create() null proto
const c = Object.create(emptyPairNullProto, { details: { value: 'new details'}, pair: {value: 'from_to'} })
Destructure null proto
const d = { ...emptyPairNullProto, details: 'new details', pair: 'from_to', }
