If you omit the comparefunction, the sort() method sorts the elements with the sort order based on the Unicode code point values of elements as mentioned earlier. We accomplish this by creating thousands of videos, articles, and interactive coding lessons - all freely available to the public. The strict equality operator checks for both value types of the two operands. JavaScript String So, the expected output is am, I, JavaScript, and learning. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded?
