This script is a client-side JavaScript library designed to sanitize HTML content. It parses untrusted HTML input and removes potentially malicious elements and attributes (like script tags, event handlers, or harmful CSS) that could lead to cross-site scripting (XSS) vulnerabilities. This ensures that only safe, whitelisted HTML tags and attributes are allowed, protecting web applications from rendering harmful user-generated content. When included on a webpage, it provides a function that developers can call to process HTML strings before they are injected into the DOM. This process enhances the security of web applications by preventing injection attacks through user-controlled input. The library operates entirely client-side and typically does not make network requests or store user-specific data itself, focusing solely on content transformation for security purposes.
