Comparison Polyfill vs jQuery

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.

jQuery is a JavaScript library that provides a wide range of features to its users. It is recognized for its speed, small size and simple API. It is available for use with many browsers on desktops such as Chrome, Edge and Firefox. It is available for use on mobile browsers as well. It is recognized for continually testing the browsers by way of unit tests. jQuery also provides its users with a jQuery Learning Center to help them understand the use of the library. jQuery also comes with a plugin registry which is available in the read-only mode. However, it no longer processes new plugin releases.
