## What it is
typeahead.js is a fast, flexible JavaScript autocomplete library from Twitter, composed of a Bloodhound suggestion engine and a jQuery-based Typeahead UI view. It provides the foundation for building robust search-as-you-type experiences in web applications.

## Use cases
- add autocomplete to a search box
- show suggestions as the user types
- build a typeahead search dropdown with jQuery
- precompute and cache suggestion datasets with Bloodhound
- implement remote and local suggestion sources

## When to choose
- your project already uses jQuery 1.9+
- you need a mature, battle-tested autocomplete with local, prefetch, and remote datasets
- you want fine-grained control over suggestion rendering and DOM interactions

## When to avoid
- you are building a modern framework app (React/Vue) where a native autocomplete component fits better
- you need mobile browser support, which is untested
- you want an actively developed library with ongoing feature work

- artifact type: library
- maturity: maintenance
- function: search-engine, ui-components, frontend-framework
- domain: web-development, frontend
