💡 Explanation:
In JavaScript, arrays are dynamic. If you assign a value to an index beyond the current length, JavaScript will create "empty" slots to fill the gap. Here, a[10] = 99 adds 1 new value at index 10, so the length becomes 11 (from index 0 to 10).

These kinds of tricks often appear in coding interviews and quizzes. Understanding array behavior is key to mastering JavaScript!
