A JavaScript polyfill implementing the Web Animations API for browsers that lack native support, falling back to native implementations when available. It unifies SVG and CSS animation features into a single programmatic API.

Use cases

• animate DOM elements with element.animate() in older browsers
• polyfill the Web Animations API for cross-browser support
• create programmatic fade and scale animations
• drive high-performance animations from JavaScript
• support legacy browsers lacking native Web Animations

When to choose

• you need Web Animations API support in older or non-supporting browsers
• you want a polyfill that defers to native implementations when available
• you need programmatic control over CSS/SVG-style animations

When to avoid

• you only target modern browsers with native Web Animations API support
• you need a full animation library with easing presets and timelines
• you need actively developed features - the project is in maintenance mode
