Benchmark: Map vs Object 123456

Script Preparation code:

const map = new Map();
const obj = {};

const count = 1000
const l = []

for (let x=0; x<=count; x++) {
  l.push([[''+x, x]])
}

function bMap() {
  'use strict'
  for (let j = 0; i+j < count; j++){
    for (let i = 0; i < count; i++) {
      const [k, v] = l[i]
      if (!map.has(k)) {
          map.set(k, v)
      } else {
          map.set(k, map.get(k)+j)
      }
    }
  }
}

function bObj() {
  'use strict'
  for (let j = 0; i+j < count; j++){
    for (let i = 0; i < count; i++) {
      const [k, v] = l[i]
      if (!obj.hasOwnProperty(k)) {
          obj[k] = v
      } else {
          obj[k] = obj[k]+j
      }
    }
  }
}
