you could put grades.length into a variable to avoid recalculating it every loop

total += grades[i];
}

let avg = total / grades.length;

does avg end up as an integer or a float? If all the grades are whole numbers, it might be an integer, but you probably want to force it to do float math

total += grades[i];
}

let avg = total / grades.length;

avg could also be const instead of a let


let avg = total / grades.length;

return avg;

instead of storing the average as a variable, you could return the calculation return value directly

Suggested change
return avg;
return total / grades.length;

total += grades[i];
}

let avg = total / grades.length;

Can delete line 9 and just do:

Suggested change
return avg;
return total / grades.length;

total += grades[i];
}

Consider renaming avg to avgGrades to be clearer.

return avg;
};

export default calculateAverage;

Might want to add a newline here

for (let i = 0; i < grades.length; i++) {
total += grades[i];
}
