Honestly; the example answer is not good. If I was in a hiring position, I would at least talk to the person writing this and ask them to change their style. The problem is that the answer is slightly over-engineered, over-commented, checks for input type, logs in a corner-case, looks-like-it-has-been-written-by-a-teacher-with-too-much-time-on-their-hands. These are not problems in themselves but when you have a new person on the team and they write code like that, it may be inconsistent with what the rest of the team is doing / what the rest of code base looks like. For comparison here is another way to test for a palindrome: function isPalindrome(text) { for (var i = 0; i <= text.length / 2; i++) { if (text[i] != text[text.length - i - 1]) return false; } return true; } (Possibly add "normalization" in the beginning as they do in the article.)
