Heads up... You've reached locked video content where the transcript will be shown astext.
In the last episode, you learned about lists. Now its time to put your new found knowledge to the test. In this challenge, I want you to create a list called grades. The grades should be 82, 76, 88, and 92. I want you store those values in the list, then calculate the average of the values. Pause the video and give it a shot.
const grades = [82, 76, 88, 92];
var sum = grades + grades + grades + grades;
var average = grades / 4;
print('the average is $average');
var sum = grades.first + grades + grades + grades;
var sum = grades.first + grades + grades + grades.last;
var average = sum / grades.length;
