這個Swift代碼的JavaScript等效代碼是什么？

Question

我了解到您可以在Swift中的類中使用數組（測驗問題示例）：

// Swift

class Question {
    var ques:String
    var ans:Bool
    var expl:String
    init(quesTitle:String, answer:Bool, explanation:String) {
        self.ques = quesTitle
        self.ans = answer
        self.expl = explanation
    }
}

class AllQues {
    var questions:[Question] = []
    init() {
        questions.append(Question(quesTitle: "Is xxx true?", answer: false, explanation: "Explanation here."))
        questions.append(Question(quesTitle: "This has to be true", answer: false, explanation: "But it isn't"))
    }
}

然后，輸出：

var allQuestions = AllQues()
func loadQuestion() {
    questionLabel.text = "Question \(number + 1) of \(allQuestions.questions.count)\n\n \(allQuestions.questions[number].ques)"
    correctAnswer = allQuestions.questions[number].ans
    explanation = allQuestions.questions[number].expl
}

我想知道JavaScript中是否有與此等效的代碼。

我正在嘗試開發時區轉換器。 這是我正在嘗試的JavaScript代碼：

// JavaScript

class City {
    constructor(city, country, offset) {
        this.city = city;
        this.country = country;
        this.offset = offset;
    }
}

class Cities {
    // ???
}

我嘗試給Cities一個包含幾個City的數組。 如您所見，Swift有一個簡單的方法。 我可以用JavaScript做類似的事情嗎？

Answer 1

class Cities {
  constructor() {
    this.cities = [];
    this.cities.push(new City("foo", "bar", "baz"));
    this.cities.push(new City("snap", "crackle", "pop"));
  }
}
