Benchmark: forEach mutate object vs map spread copy

Script Preparation code:

const objects = [
  { a: 'XzWtv', b: 'sFqrG', c: 'qCbnP' },
  { a: 'yjkAu', b: 'vMhlE', c: 'xPqro' },
  { a: 'wNztX', b: 'gDypR', c: 'iHklL' },
  { a: 'mQjvs', b: 'dKzpt', c: 'aVbcO' },
  { a: 'bUefZ', b: 'cRiyG', c: 'uTqxs' }
]

Tests:

edit field with map and spread
objects.map(el => ({...el, d: Math.random()}))
edit field with forEach and mutation
objects.forEach(el => {el.d = Math.random()})
