Creating meaningful animations with JavaScript
summary
Shows how IBM teams use Carbon Design System plus an IBM motion generator to design UI motion that meets performance targets: aim for 60fps (16.6ms per frame), answer input within 50ms, and budget ~10ms per animation frame. Implements a demo that clones a list item, computes start/end positions and a Bezier path, uses requestAnimationFrame and transform instead of left, then animates along the curve with offset-path and the Web Animations API, and adjusts duration from curve length so the motion feels consistent across distances and devices.
