What are the key differences between Jehovah's Witnesses and Latter-day Saints in terms of their beliefs and practices?

Jehovah's Witnesses and Latter-day Saints have different beliefs and practices. Jehovah's Witnesses focus on door-to-door evangelism, reject the Trinity, and do not celebrate holidays or birthdays. Latter-day Saints believe in modern prophets, have additional scriptures like the Book of Mormon, and practice baptism for the dead.
