-      The output is going to be `33`. Since `1` and `2` are numeric values, the result of the first two digits is going to be a numeric value `3`. The next digit is a string type value because of that the addition of numeric value `3` and string type value `3` is just going to be a concatenation value `33`. Other operationrs like `3 * '3'` do yield correct results because the string is coerced into a number.

 ##### Answer: 3
 
-Javascript has a native method sort that allows sorting an array of elements in-place. It will treat each element as a string and sort it alphabetically. But if you try to sort an array of strings which has non-ASCII characters, you will receive a strange result. This is because characters with an accent have higher character codes.

 In this case, the sort order of an array is ['Wann', 'Woche', 'wäre', 'wöchentlich'].
