FAQ
List Sorter & Deduplicator: questions
Does order matter when I deduplicate?
The first occurrence of each line is kept; subsequent duplicates are removed. Sort first if you want the deduplication to be case-sensitive.
Is the shuffle truly random?
It uses the Fisher-Yates algorithm with Math.random() — sufficient for everyday use but not cryptographically secure.
