Benchmark: testing ternary vs &&

Script Preparation code:

function translateBySpread (a) {
  const b = {
    ...(a.id && { id: a.id }),
    ...(a.foo && { foo: a.foo})
  }
  return b;
}

function translateByTernary (a) {
  const b = {
    ...(a.id ? { id: a.id } : {}),
    ...(a.foo ? { foo: a.foo} : {})
  }
  return b;
}

Tests:

spread ternary
translateByTernary({ id: '12345', type: 'article' });
spread &&
translateBySpread({ id: '12345', type: 'article' });
