JavaScript Rendering

JavaScript rendering refers to executing a webpage's JavaScript code to produce the final visible HTML.

Many modern websites (React, Vue, Angular apps) serve nearly empty HTML and populate content via JavaScript. Scrapers need JavaScript rendering to access this dynamically loaded content — typically done via a headless browser.
