## Description

highlight.js is a JavaScript syntax highlighter and client-side code formatter that transforms plain text source code into highlighted HTML for web display. It provides syntax highlighting across a wide variety of programming languages.

The library includes an automatic language detector that identifies the programming language of a code block to apply the correct highlighting rules without manual tagging. It is designed for web worker compatibility, allowing the highlighting process to run in background threads to prevent the browser interface from freezing during the processing of large volumes of code.

This zero-dependency runtime handles both automatic and manual language specification to format source code directly in the browser.
