BrowserSync
BrowserSync is a development tool that synchronizes browser behavior across multiple devices and browsers in real-time. It automatically refreshes the browser when files are changed, and supports features like CSS injection, form input synchronization, and scroll mirroring. It is commonly used during web development to streamline testing and improve workflow efficiency.
Developers should use BrowserSync when building responsive websites or web applications that require testing across different browsers and devices simultaneously. It is particularly useful for front-end development to ensure consistency and save time by eliminating manual refreshes, making it ideal for projects involving HTML, CSS, and JavaScript where rapid iteration is needed.
