생활코딩 자바스크립트 this, prototype 강의를 보고 만든 예제

var student001 = {
    name: 'sherlock',
    scoreA: 90,
    scoreB: 80,
    scoreSum: scoreSum
};

var student002 = {
    name: 'lily',
    scoreA: 80,
    scoreB: 70,
    scoreSum: scoreSum
};

function scoreSum () {
    return `name: ${this.name}, total: ${this.scoreA + this.scoreB}`;
}

console.log(student001.scoreSum());
console.log(student002.scoreSum());
