javascriptweb developmentfront end technologyobject oriented programming
我们需要编写一个函数，找到传递给它的三个分数的平均值，并根据下表返回与该成绩相关的字母值。
示例
const findGrade = (...scores) => {
const {
length
} = scores;
const sum = scores.reduce((acc, val) => acc + val);
const score = sum / length;
if (score >= 90 && score <= 100) {
return 'A';
}
else if (score >= 80 ) {
return 'B';
} else if (score >= 70 ) {
return 'C';
} else if (score >= 60) {
return 'D';
} else{
return 'F';
};
}
console.log(findGrade(5,40,93));
console.log(findGrade(30,85,96));
console.log(findGrade(92,70,40));
输出
控制台中的输出将是 −
F C D
