A '''bookmarklet''' is a [[Bookmark (digital)|bookmark]] stored in a [[web browser]] that contains JavaScript commands that add new features to the browser. They are stored as the [[Uniform Resource Locator|URL]] of a bookmark in a [[web browser]] or as a [[hyperlink]] on a [[web page]]. Bookmarklets are usually small snippets of [[JavaScript]] executed when user clicks on them. When clicked, bookmarklets can perform a wide variety of operations, such as running a search query from selected text or extracting data from a table.

Another name for ''bookmarklet'' is '''favelet''' or '''favlet''', derived from ''favorites'' (synonym of bookmark).<ref>{{cite web |url=https://www.levelaccess.com/how-to-create-a-favlet-for-accessibility-testing/ |title=How to create a favlet for accessibility testing |author=Jonathan Avila <!-- random example, 2nd search hit for me after [[:en:Favlet]] --> |date=2014-03-02 |access-date=2023-05-23 |archive-date=2018-01-22 |archive-url=https://web.archive.org/web/20180122133139/https://www.levelaccess.com/how-to-create-a-favlet-for-accessibility-testing/ |url-status=dead}}</ref>
