Suggest a word when there is a typo

A lookup is exact: loadWords("arigatuo") finds nothing. suggestWords answers with the common words whose reading is one slip away from what was typed, so that a page can say "Did you mean ありがとう?".

Ask for suggestions

import { suggestWords } from "@johnmorrisdotca/jisho/words";

for (const { word, distance } of await suggestWords("arigatuo")) console.log(word.written, distance);

ありがとう 1

A slip is a letter (or kana) too many, too few, wrong, or two neighbours the wrong way round. A text of romaji is read as romaji and its slips are slips of letters (nihonngo, ohayou gozaimsu); a text of kana has slips of kana (にほんこ). The words come exact first (distance 0) and then one slip away (distance 1), the commonest first. limit is how many, 5 unless given and 20 at most. It takes the same mode, block and allow as a lookup, and in safe mode a word that safe mode leaves out is not suggested.

What it covers

It reads the table of the common words, 26,014 of them, which it fetches once (about 800 kB gzipped, a second file in unfiltered mode), so it suggests only common words, and only by their reading: a text of kanji suggests nothing, since a kanji is not a slip away from another, and a conjugated form that is not a word of the dictionary (tabemsu for 食べます) is not found either; look the dictionary form up with findInflected when the exact text finds nothing, and ask for suggestions when that finds nothing too. It is for a lookup that found nothing, not for every lookup.
