我想知道如何检查属性字段是否为真，然后使用javascript将字符串推到数组中

• 如果kid为真，则压入字符串kidexists，
• 如果country为真，则压入字符串cnexists，
• 如果details为真，则压入字符串dtsexists，

尝试的代码：

var itemList1 = [
  {id:1, kid: true, country: true, details: false},
  {id:2, kid: true, country: false, details: true},
  {id:3, kid: true, country: false, details: false}
]

var itemList2 = [
  {id:1, kid: false, country: true, details: false},
  {id:2, kid: true, country: false, details: false},
]

var r1 = this.result(itemList1)
var r2 = this.result(itemList2)

console.log("R1:", r1);
console.log("R2:", r2);

function result(items){
  let finalResult=[]
  for (let i of items) {
    if (i.kid) {
      finalResult.push('kidexists');
    } else if (i.country) {
      finalResult.push('cnexists');
    } else if (i.details) {
      finalResult.push('dtsexists');
    }
    finalResult =  [...new Set(finalResult)];
    return finalResult;
  }
}

itemList1的预期输出

['kidexists', 'cnexists', 'dtsexists'];

itemList2的预期输出

['kidexists', 'cnexists'];
