Javascript 函数是否应该避免通过三元条件拒绝承诺?

Should a Javascript function avoid reject a promise via a ternary condition?

我看到了一段我觉得很有趣的代码。感觉这里有很多问题。我在这里看到一个三元组返回错误而不是值吗?因此,这不应该是 if-else 吗?

const aData = await response.json();
return await new Promise((resolve, reject) => {
  (aData.title === aName)
    ? resolve('A data was found')
    : reject(new Error('Incorrect data was returned'));
});

resolvereject 都只是 return 值 undefined,而您的回调函数根本没有 return 任何东西。使用三元运算符使其成为单个表达式是没有用的。
为了清楚起见,你最好写

if (aData.title === aName) resolve('A data was found');
else reject(new Error('Incorrect data was returned'));

尽管您根本不应该在这里使用 new Promise 构造函数。刚刚

const aData = await response.json();
if (aData.title !== aName) throw new Error('Incorrect data was returned');
else return 'A data was found';
