## What it is
mark.js is a JavaScript library for highlighting keywords or custom regular expressions in text, usable with plain JavaScript or as a jQuery plugin. It offers options like diacritics support, separate word search, synonyms, iframes support, custom filters, and custom element/class names.

## Use cases
- highlight search terms in search results
- mark keywords in a page dynamically
- highlight text matching a custom regular expression
- filter a list and highlight matching entries
- build a search bar that jumps to matches
- highlight matches inside table columns

## When to choose
- you need client-side keyword or regex highlighting in the browser
- you want configurable matching (diacritics, synonyms, word boundaries, accuracy)
- you need both vanilla JS and jQuery integration options

## When to avoid
- you need server-side or non-DOM text highlighting
- you want syntax highlighting for source code rather than keyword marking
- your project no longer uses jQuery and you need a framework-specific solution

## Facets
- artifact type: library
- maturity: stable
- function: search-engine, ui-components, parser
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: keyword-highlighting, jquery-plugin, text-marking, search-term-highlight, dom-manipulation, search, nodejs
