hljshighlightBlock

hljshighlightBlock is a JavaScript function associated with the highlight.js library, a syntax highlighter for the web. Its primary purpose is to automatically detect and highlight code blocks present on a webpage. When included in a web project, hljshighlightBlock scans the Document Object Model (DOM) for elements that are typically used to contain code, such as `<pre>` and `<code>` tags. It then analyzes the content within these elements to determine the programming language being used. Once the language is identified, highlight.js applies CSS classes to the code, enabling a pre-defined or custom theme to style the syntax, making it more readable and visually distinct. This function is often called after the DOM has loaded to ensure all code blocks are processed. It simplifies the process of adding syntax highlighting to websites, requiring minimal configuration for basic usage. Developers can customize its behavior by specifying target elements or excluding certain code blocks if needed.
