我如何将用户的答案存储在一个数组中，以便它可以检查正确的答案

// 假设这是正确答案数组
const correctAnswers = ['A', 'B', 'C', 'D'];

// 用于存储用户答案的数组
let userAnswers = [];

// 假设我们有一个函数来获取用户的答案
function getUserAnswer(questionIndex) {
    // 这里可以是从表单获取或用户输入等方式
    return prompt(`请输入第${questionIndex + 1}题的答案:`);
}

// 获取所有用户的答案并存储在数组中
for (let i = 0; i < correctAnswers.length; i++) {
    userAnswers.push(getUserAnswer(i));
}

// 检查答案的正确性
let score = 0;
for (let i = 0; i < correctAnswers.length; i++) {
    if (userAnswers[i] === correctAnswers[i]) {
        score++;
    }
}

console.log(`你答对了 ${score} 题`);

// 异步获取用户答案的示例
async function getUserAnswersAsync() {
    let userAnswers = [];
    for (let i = 0; i < correctAnswers.length; i++) {
        userAnswers.push(await getUserAnswerAsync(i));
    }
    return userAnswers;
}

async function getUserAnswerAsync(questionIndex) {
    return new Promise((resolve) => {
        setTimeout(() => {
            resolve(prompt(`请输入第${questionIndex + 1}题的答案:`));
        }, 100); // 模拟异步延迟
    });
}

// 使用async/await处理异步答案获取
(async () => {
    const userAnswers = await getUserAnswersAsync();
    let score = 0;
    for (let i = 0; i < correctAnswers.length; i++) {
        if (userAnswers[i] === correctAnswers[i]) {
            score++;
        }
    }
    console.log(`你答对了 ${score} 题`);
})();
