What each one is
Select2
Select2 is a JavaScript component that replaces the standard dropdown (select) box on a web page with a more capable one. It adds search, lets options be loaded from remote data sources, and supports loading more results as the user scrolls. It is built on jQuery and is typically included on a page from a CDN or installed as a package.
typeahead.js
typeahead.js is a JavaScript library for adding autocomplete (typeahead) suggestions to a text input on a web page. It has two parts: Bloodhound, which computes suggestions for a query, and a UI view that renders the suggestions and handles user interaction in the page. The parts can be used separately or together.
Best for
Select2
- Web developers who already use jQuery and want a better dropdown
- Sites with long option lists that need search
- Forms that load options from a server through AJAX
- Projects using a CMS or framework integration listed in the README
typeahead.js

Strengths
Select2
- Covers common needs like search, tagging, and remote data in one component
- Works as a drop-in enhancement for existing select elements
- MIT licensed and widely integrated with platforms such as Django, Drupal, and Rails
typeahead.js
- Two components that can be used separately or together
- Listed browser support reaches back to older browsers such as IE 8+
- MIT licensed
Not ideal for
Select2
- Projects that do not use jQuery, since the library is built on it and the README does not describe a non-jQuery version
- Non-developers who want a finished tool without writing any code
- Situations where a plain native select element is enough
typeahead.js
- Projects needing mobile browser support, since the README says it is not tested on mobile browsers
- Projects that do not use jQuery, since the UI view and Bloodhound require jQuery 1.9+ according to the README
- Non-developers looking for a ready-made app, since this is a code library
Trade-offs
Select2
- Depends on jQuery, which may be an unwanted dependency in modern projects
- README lists older browser support (IE 8+), which may be more than needed today
- Latest release shown is 4.1.0 with no binaries; usage is through CDN or source files
typeahead.js
- README states dependency on jQuery 1.9+ and no mobile browser testing
- Last push in the metadata is from April 2023, and no release is listed, so current maintenance status is unclear
- README has limited detail in the excerpt provided, so usage specifics are in linked docs not reviewed here
