23,932 PointsIs it possible to .set() many key/value pairs all in one line?
For example....
sarah.grades.set('History', 'B' 'Math', 'A' 'Geography', 'C');
My code in the example is obviously wrong, but used to illustrate what I am trying to figure out. Can we do this on one line instead of having to write on three separate lines?

sarah.grades.set('History', 'B').set('Math', 'A').set('Geography', 'C');
