object spread
let obj = {}; for(i=0;i<100;i++){ const key = 'key'+i const value = 'value'+i obj = {...obj, [key]: {key, value}} }
immutable-js
let obj = Immutable.Map(); for(i=0;i<100;i++){ const key = 'key'+i const value = 'value'+i obj = obj.set(key, {key, value}) }
native Map
let obj = new Map(); for(i=0;i<100;i++){ const key = 'key'+i const value = 'value'+i obj = new Map(obj); obj.set(key, {key, value}) }
