Reduce with deconstruction or forEach - Iteration and Airbnb JavaScript Style Guide

I have an object:

things = {
  table: 'red',
  chair: 'green'
}

Adhering to Airbnb's JavaScript Style Guide, I want to create a function that duplicates this object, setting all keys of the object to blue.

My 2 options seem to be:

1 Use reduce

function alwaysBlue(things) {
  return Object.keys(things)
    .reduce((acc, thing) => ({ ...acc, [thing]: 'blue' }), {})
}

2 Use forEach

function alwaysBlue(things) {
  const blueThings = {}
  Object.keys(things)
    .forEach(thing => (blueThings[thing] = 'blue'))
  return blueThings
}

(1) deconstruction on every iteration seems expensive, but if I'm to take no-param-reassign in to account I can't just append to the accumulator on each iteration

However, forEach (2) should be avoided in favour of map() / every() / filter() / find() / findIndex() / reduce() / some(), according to https://github.com/airbnb/javascript#iterators--nope

So which is the preferred approach if I'm to adhere to Airbnb's JavaScript Style Guide - or is there another approach I'm missing?
