I tried using existing fuzzy libraries like fuse.js and also found them to be terrible, so I wrote one which behaves basically like sublime’s search. https://github.com/farzher/fuzzysort
The only typo it allows is a transpose. It’s pretty solid (1k stars, 0 issues), very fast, and handles your case easily:
fuzzysort.go('int', ['international', 'splint', 'tinder'])
// [{highlighted: '*int*ernational', score: 10}, {highlighted: 'spl*int*', socre: 3003}]
