var testScores testScores0 80 82 90 87 85 testScores1 79

var testScores = [];

testScores[0] = [80, 82, 90, 87, 85];
testScores[1] = [79, 80, 74, 82, 81];
testScores[2] = [93, 95, 89, 100, 85];
testScores[3] = [60, 72, 65, 71, 79];

This code creates a tabular structure that has

5 rows and 4 columns

4 rows and 5 columns

4 rows and 4 columns

5 rows and 5 columns

Solution

Here is the given structure:-

var testScores = [];

testScores[0] = [80, 82, 90, 87, 85];
testScores[1] = [79, 80, 74, 82, 81];
testScores[2] = [93, 95, 89, 100, 85];
testScores[3] = [60, 72, 65, 71, 79];

And this will create a tabular structure that has 4 rows and 5 columns
