## What it is
A JavaScript/TypeScript library that filters and sorts arrays of items by best match against a query string, using a deterministic ranking algorithm (case-sensitive equals, starts-with, acronym, etc.). It is commonly used to power autocomplete and filter inputs.

## Use cases
- filter a list of items as the user types in a search input
- sort autocomplete suggestions by best match
- implement fuzzy search over an array of objects
- rank dropdown options intuitively in a combobox
- search a list of countries or names with acronym matching

## When to choose
- you need simple, deterministic, user-friendly filtering and ranking of in-memory lists
- you want a tiny utility for autocomplete or filter inputs
- you need sensible ranking like starts-with, word-starts-with, and acronym matching without tuning a fuzzy-search algorithm

## When to avoid
- you need full-text search over large datasets or an index (use a search engine like Lunr or Elasticsearch)
- you need typo-tolerant or similarity-scored fuzzy matching rather than rank-based matching
- your data lives on a server and should be filtered server-side
