Polyfill is a technology that provides modern functionality to older, less advanced web browsers or environments, ensuring consistent and efficient user experience. Essentially, it is a fallback mechanism designed to fill in the gaps in browser compatibility by mimicking the API features of recent web standards. By using JavaScript code libraries or plugins, Polyfill identifies the browser's incapabilities and adapts accordingly, essentially "polyfilling" missing features. This technique enables developers to leverage the latest technologies without alienating users of older browsers, maintaining support, and ensuring a seamless integration of innovative web features.
