Script Preparation code:

var l = _.range(1000).reduce( (acc, i) => ({...acc, i:  { id: i, name: 'test' }}), {} )
var r = _.range(40).reduce((acc, i) => ({...acc, i: { id: i, name: "test" + i }}), {} )

var mergeMapsOfRecords = (obj1, obj2) => {
  const l = obj1 || {}
  const r = obj2 || {}

  const keys = Object.keys(r)

  const newMap = { ...l }

  for (const key of keys) {
    if (l.hasOwnProperty(key) && r.hasOwnProperty(key)) {
      newMap[key] = { ...l[key], ...r[key] }
    } else {
      newMap[key] = r[key]
    }
  }

  return newMap
}
