Javascript 如何使用reduce增加对象数组中的关键点？

我试图减少一个对象数组，使其具有一个boss键，并增加伙伴忠诚度。但是，我一直得到一个没有唯一键的对象数组。我尝试检查对象键是否在那里，然后检查对象键是否在那里。但尚未成功增加Sidekick忠诚度值

预期产出

[
  { bossName: 'Jafar', sidekickLoyalty: 3 },
  { bossName: 'Ursula', sidekickLoyalty: 20 },
  { bossName: 'Scar', sidekickLoyalty: 16 }
]

bossLoyalty() {
  let bossyBoss = sidekicks.reduce((totalLoyalty, sidekick) => {
  let bossObject = {
    bossName: null,
    sidekickLoyalty: 0
  };
  if (!bossObject.bossName) {
    bossObject.bossName = sidekick.boss;
  }
  if(bossObject.bossName === sidekick.boss) {
    bossObject.sidekickLoyalty += sidekick.loyaltyToBoss;
  }
  totalLoyalty.unshift(bossObject);
  return totalLoyalty;
}, [])
const result = bossyBoss;
return result;
}

const sidekicks = [
{
  name: 'Shenzi',
  associates: ['Banzai', 'Ed'],
  strengths: ['leadership', 'sass'],
  boss: 'Scar',
  loyaltyToBoss: 4
},
{
  name: 'Banzai',
  associates: ['Shenzi', 'Ed'],
  strengths: ['strategy', 'suspicion'],
  boss: 'Scar',
  loyaltyToBoss: 5
},
{
  name: 'Ed',
  associates: ['Shenzi', 'Banzai'],
  strengths: ['unknown'],
  boss: 'Scar',
  loyaltyToBoss: 7
},
{
  name: 'Flotsam',
  associates: ['Jetsam'],
  strengths: ['spying', 'manipulation', 'flipping boats'],
  boss: 'Ursula',
  loyaltyToBoss: 10
},
{
  name: 'Jetsam',
  associates: ['Flotsam'],
  strengths: ['spying', 'manipulation', 'flipping boats'],
  boss: 'Ursula',
  loyaltyToBoss: 10
},
{
  name: 'Iago',
  associates: [],
  strengths: ['mimicry', 'critical'],
  boss: 'Jafar',
  loyaltyToBoss: 3
}
];

当前结果

[
 { bossName: 'Jafar', sidekickLoyalty: 3 },
 { bossName: 'Ursula', sidekickLoyalty: 10 },
 { bossName: 'Ursula', sidekickLoyalty: 10 },
 { bossName: 'Scar', sidekickLoyalty: 7 },
 { bossName: 'Scar', sidekickLoyalty: 5 },
 { bossName: 'Scar', sidekickLoyalty: 4 }
]
