`@xobotyi/scrollbar-width` is a lightweight JavaScript utility that measures the width of browser scrollbars, providing consistent values across different browsers and environments. It's designed for developers building UI components or layouts where precise scrollbar dimensions are needed, such as custom scrollbars, modal overlays, or responsive designs. The tool caches results for performance but allows forced recalculation when needed, making it ideal for web applications that require accurate scrollbar measurements.
