Autocomplete seems like one of the easiest features to build. You take the user's input, loop through your list of options, and filter anything that starts with the same prefix: const matches = words.filter(w => w.startsWith(prefix)); And that works for small lists of text. But once your dataset gets large, or your completions come from structured text (like user.address.city or $gte), simple loops start to fall short.
