Javascript 如果条件运行即使为false，也很混乱

我有下面的代码，在代码块的末尾有一个if语句，但即使它是false，after代码仍然运行，数据被添加到MongoDB中。我不明白为什么

当我通过发送get请求来测试它时，这些项会被添加到MongoDB中

const router = require('express').Router();
const xml2js = require('xml2js');
const Avaya = require('../../models/avayaLogs')

router.route('/').get(async (req, res) => {

    const axios = require("axios");
    const getData = axios( {
        url: "http://127.0.0.1:60000/onexagent/api/nextnotification?clientid=65e814f0-e7d8-4404-b9e5-203bfc7935c5",
    })

    const data = await getData;
    const converted = xml2js.parseStringPromise(data.data, { mergeAttrs: true })
    .then(result => result);
    const logs = await converted;
    const notifType = []
    const notifDetails = []


    for (let i in logs.NextNotificationResponse) {
        notifType.push(i)
    }

    for (let i in logs.NextNotificationResponse[notifType[1]][0])
    {notifDetails.push(i)}

    const arranged = {
        NotificationType: notifType[1],
        ResponseCode: logs.NextNotificationResponse[notifType[0]][0]
    }

    for (let i = 0; i < notifDetails.length; i++)
        {
        arranged[[notifDetails[i]][0]]= logs.NextNotificationResponse[notifType[1]][0][notifDetails[i]][0]
        }
        console.log(arranged)




    if (arranged.NotificationType === 'VoiceInteractionCreated' || 'VoiceInteractionMissed' || 'VoiceInteractionTerminated') {
        const newLogs = new Avaya({
            notification: arranged

        });

        newLogs.save()
        .then(logs => res.json(logs))
        .catch(err => console.error(err));
    }


});

module.exports = router;

您应该分别比较它们：

if (arranged.NotificationType === 'VoiceInteractionCreated' || arranged.NotificationType === 'VoiceInteractionMissed' || arranged.NotificationType === 'VoiceInteractionTerminated')

您应该分别比较它们：

if (arranged.NotificationType === 'VoiceInteractionCreated' || arranged.NotificationType === 'VoiceInteractionMissed' || arranged.NotificationType === 'VoiceInteractionTerminated') 

在上面的代码中，我添加了一些括号，告诉您为什么它会返回true。Javascript中考虑了字符串

这将为您提供所需的输出

if (arranged.NotificationType === 'VoiceInteractionCreated' || arranged.NotificationType === 'VoiceInteractionMissed' || arranged.NotificationType === 'VoiceInteractionTerminated') {

arranged.NotificationType===“VoiceInteractionCreated”| |“VoiceInteractionMissed”| | |“VoiceInteractionTerminated”不是检查多个值的有效方法。“Foo”| |“Bar”始终为真。arranged.NotificationType===“VoiceInteractionCreated”| |“VoiceInteractionMissed”| |“VoiceInteractionTerminated”不是检查多个值的有效方法。“Foo”| |“Bar”永远是真的。
