Benchmark: convert and lookup 10k times and 10k items

Script Preparation code:

var objList= [
  { name: "Lorem" },
  { name: "ipsum" },
  { name: "dolor" },
  { name: "sit" },
  { name: "amet" },
  { name: "consectetur" },
  { name: "adipisicing" },
  { name: "elit." },
  { name: "Ullam" },
  { name: "nesciunt" },
  { name: "debitis," },
  { name: "facilis" },
  { name: "qui" },
  { name: "possimus" },
  { name: "minus" },
  { name: "rerum" },
  { name: "velit" },
  { name: "saepe" },
  { name: "magnam," },
  { name: "voluptatum" },
  { name: "quos" },
  { name: "eveniet" },
  { name: "ducimus" },
  { name: "facere" },
  { name: "harum" },
  { name: "itaque" },
  { name: "atque" },
  { name: "assumenda" },
  { name: "reiciendis" },
  { name: "exercitationem" }
]

for(let i = 0; i < 100000; i++)
  objList.unshift({ name: ""+i })

Tests:

Object lookup
var object = objList.reduce((acc, team) => { acc[team.name] = team return acc; }, {}); var b = object["consectetur"]
Map lookup
var map = objList.reduce((acc, team) => { acc.set(team.name, team); return acc; }, new Map()); for(let i = 0; i < 100000; i++) var b = map.has("consectetur")
Set lookup
var set = objList.reduce((acc, team) => { acc.add(team.name); return acc; }, new Set()); for(let i = 0; i < 100000; i++) var b = set.has("consectetur")
