Fast search, filter & sort for large client-side collections in JavaScript

Hey everyone! I'd like to share an npm package I built for working with large collections of 100K+ items on the client side. The problem Sometimes the server sends back a huge array 100K+ items. And you need search, filter, and sort on the client side. The issue is that standard JS methods like .filter() or .sort() go through the whole array every time.
