There is another aspect of tries that make them really useful: you can do fast, fuzzy word searches on a trie.

In Typesense[1], I've implemented fuzzy search based on levenshtein damerau distance and it's incredibly fast. I've found this approach to be a much better (faster + more flexible) alternative to Peter Norvig's brute-force based spell-checker that is quite a popular post [2].
