The result in the exercise for chapter 5 for
sumAToB(0, -15);
// //=> 120
is wrong. It should be -120. Seems like a typo. Test passes in Jasmine Spec runner and the test indicates the result is -120.
// Write a function called `sumAToB` so that it accepts two parameters
// `a` and `b` and sums the numbers between `a` and `b` inclusive. Note
// that `a` may be larger than `b`, in which case you'll need to work
// backawards.
//
// sumAToB(10, 20);
// //=> 165
//
// sumAToB(0, -15);
// //=> 120
//
// sumAToB(-10, 500);
// //=> 125195
//
// sumAToB(10, 10);
// //=> 10
// sumAToB("hello", "world");
// //=> inputs should be numbers!
//
var sumAToB = function (a , b) {
};

practice exercises |
in the practice exercises for Arrays , exercise getValuesAppearingTwice
the exercise specifies to :
Create a new function that returns an array of only the values from the first array that appear twice in the second array.
however the tests are only using 1 array as input.

4th exercise |
Doing the overview exercise for the chapter on while and for loops. In the practice.js file the fourth exercise: sumAToB.
the sum of all values between 0 and -15 should result in the negative number -120. unless you want to take the absolute values and do the calculations with that. In that case sumAToB(-10, 500) has the wrong outcome and it should be: 125205.
Up to this point in the course you have not yet told about Math.abs() so I guess you made a slight typo there.
So far I like the course.
