I have written a function that takes an array of objects(students3) and prints the name of the student and their average test score.
var students3 = [
{
name : "Anthony",
id : 0,
grades : [{ id : 0, score : 84},{ id : 1, score : 20},{ id : 2, score : 80}]
},
{
name : "Winnie",
id : 1,
grades : [{ id : 0, score : 62},{ id : 1, score : 56},{ id : 2, score : 100}]
},
{
name : "Pawandeep",
id : 2,
grades : [{ id : 0, score : 79},{ id : 1, score : 92},{ id : 2, score : 49}]
}
];My solution:
function getAverageScore(student)
{
var sum = 0;
var grades = student.grades;
for(var i = 0; i < grades.length; i++)
{
var grade = grades[i];
sum += grade.score;
}
var avg = sum/grades.length;
return avg;
}
function printAverageGrade(students)
{
for(var i = 0; i < students.length; i++)
{
var student = students[i];
var averageScore = getAverageScore(student);
console.log(student.name, averageScore);
}
} Expected result after running console.log(printAverageGrade(students3)); is:
Anthony 61.333333333333336
Winnie 72.66666666666666
Pawandeep 73.33333333333333
My result:
Anthony 61.333333333333336
Winnie 72.66666666666666
Pawandeep 73.33333333333333
undefined
Anyone can tell me why I am getting an undefined value in my result? Thank you.
