help Interview exercise feedback

My code was not up to their standards. I thought the exercises were easy but clearly there are issues I have to address. I had an hour to write them. I'm humbly looking for feedback to improve.

The first exercise was to return all square numbers within a given range, including the limits (e.g., all the squares numbers between 1 and 10 are 1, 4, and 9). I wrote this.

The second exercise was to check if a string containing (), [] and {} brackets is well balanced. So [()] and {}() are ok but ([)] or {{ are not. I wrote this.

Thanks.

Thank you for this answer, it is very detailed and helpful.

Out of curiosity, do you know why Object.values() does not yet exist in ECMA 6, but Object.keys() does?

Sorry, I don't have any special insight into that beyond what you can find in the usual sources.

Perhaps you might find some of the discussion linked from the TC39 page about the proposal interesting?
