用js写一个学生成绩考评

在JavaScript中，我们可以创建一个简单的学生成绩考评类（StudentGradeEvaluator），这个类可以包含学生的姓名、课程列表以及计算总分和平均分的方法。以下是一个基础的例子：

class StudentGradeEvaluator {
    constructor(name) {
        this.name = name;
        this.grades = {}; // 使用对象存储每个课程的成绩
    }

    addCourse(course, grade) {
        if (grade >= 0 && grade <= 100) { // 确保成绩在合理范围内
            this.grades[course] = grade;
        } else {
            console.log(`Invalid grade for ${course}. Grade should be between 0 and 100.`);
        }
    }

    calculateTotalScore() {
        let total = 0;
        Object.values(this.grades).forEach(grade => total += grade);
        return total;
    }

    calculateAverageScore() {
        const total = this.calculateTotalScore();
        if (Object.keys(this.grades).length > 0) {
            return total / Object.keys(this.grades).length;
        } else {
            return 0; // 如果没有成绩，返回0
        }
    }

    printReport() {
        console.log(`Name: ${this.name}`);
        console.log("Courses and Grades:");
        for (const [course, grade] of Object.entries(this.grades)) {
            console.log(`${course}: ${grade}`);
        }
        console.log(`Total Score: ${this.calculateTotalScore()}`);
        console.log(`Average Score: ${this.calculateAverageScore()}`);
    }
}

// 使用示例
const student = new StudentGradeEvaluator("张三");
student.addCourse("数学", 95);
student.addCourse("英语", 85);
student.printReport();
