Comparison AOS vs Polyfill

AOS (Animate on Scroll) is a library, created by Michał Sajnóg. It is commonly used by animators for their animation projects. AOS Library is based on CSS/JS. It allows animators to create different animation effects such as fade animations, flip animations, slide animations, zoom animations, anchor placements and easing functions. It provides customization as well. AOS Library provides data attributes such as data-aos-offset, data-aos-duration and data-aos-easing that enables animators to configure their animations with ease. AOS is characterized by its user-friendliness and flexibility. AOS Library can be installed through Bower or npm. It also requires the necessary scripts and sheets from UNPKG.

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.
