dont understand why has dave used numbers as strings in students array for the points and achievements?

on the 1st object he used numbers as numbers but rest of the objects he put quote marks around numbers .... why? i havent changed them to strings, and it worked fine but wondering as i am proceeding towards the student search challenge... would it cause any issues then?

Good eye! I didn't notice that when I took this course, and it is quite curious. But it won't cause any problem just for printing things out or finding students by name.

But it could indeed be a problem if you were to later write some code that did some math on the values (such as compute an average) or if it did comparisons between the student records.

Yep! Came here to ask the same thing! Second time today he tells you to do something as he does something different in the exercise.

I was also curious about the mixing of strings and values for some of the properties.

copy that! Is it because a JSON-format should be in string but is formed in such as way it can be use as JS ?

Also was wondering about this, in the first pair of numbers he does not use a string, and then uses a string for the rest of them. Kind of confusing, but I see it works either way.
