Given this paragraph about ext3, tell me why its better than ext2 and its successor.

Context: ext3, or third extended filesystem, is a journaled file system that is commonly used by the Linux kernel. It used to be the default file system for many popular Linux distributions. Stephen Tweedie first revealed that he was working on extending ext2 in Journaling the Linux ext2fs Filesystem in a 1998 paper, and later in a February 1999 kernel mailing list posting. The filesystem was merged with the mainline Linux kernel in November 2001 from 2.4.15 onward. Its main advantage over ext2 is journaling, which improves reliability and eliminates the need to check the file system after an unclean shutdown. Its successor is ext4

Answer: ext3 is better than ext2 because of its journaling capabilities, which improve reliability and eliminates the need to check the file system after an unclean shutdown. The successor of ext3 is ext4.
