Web Animations API

ELI5 — The Vibe Check

The Web Animations API lets you do CSS animations and transitions from JavaScript, with full control over playback. Pause, reverse, speed up, seek to any point - it's like having a remote control for animations. No library needed, it's built into the browser.

Real Talk

The Web Animations API provides a JavaScript interface for creating and controlling animations, unifying CSS Animations and CSS Transitions under a single programmatic model. It offers fine-grained control over animation playback, timing, and compositing directly through the browser engine.

element.animate(
  [{ transform: 'scale(1)' }, { transform: 'scale(1.5)' }],
  { duration: 300, easing: 'ease-out', fill: 'forwards' }
);
