javascript - 如何使用 Inquirer 使我的 "if else"语句在此 Node 文件中正常工作？

Question

我正在尝试获取一些代码，以便根据他们对问题给出的答案在屏幕上显示特定的消息。这是一个使用 Inquirer 包的 Node 应用程序，每次我运行该 Node 应用程序时，它都会返回“未定义”。

{
        type: "checkbox",
        name: "channels",
        message: "Which of these TV channels would you watch?!",
        choices: ["Investigation Discovery", "CNN", "Fox News", "TLC"]
    }
]).then(function (responses) {
    for(let i = 0; i < responses.channels; i++) {
        if (responses.channels === 0) {
            console.log("You are probably smart");
        }`enter code here`
        else if (responses.channels === 1) {
            console.log("You are probably well informed");
        }
        else if (responses.channels === 2) {
            console.log("You are probably not very well informed");
        }
        else {
            console.log("You are probably an idiot");
        }
    }

如前所述，它应该根据选择的选项在控制台中返回一条消息，但它只会返回“未定义”。

好的，我自己解决了。这是我需要做的:

    if (responses.channels = 1) {
        console.log("You are probably smart");
    }
    else if (responses.channels = 2) {
        console.log("You are probably well informed");
    }
    else if (responses.channels = 3) {
        console.log("You are probably not very well informed");
    }
    else {
        console.log("You are probably an idiot");
    }
