## What it is
interact.js is a standalone JavaScript library for drag and drop, resizing, and multi-touch gestures with inertia and snapping, supporting HTML and SVG elements across modern browsers and IE9+. It provides a unified pointer-event API without moving DOM elements itself, leaving visual feedback entirely to the developer.

## Use cases
- add drag and drop to web app elements
- implement resizable panels in the browser
- handle multi-touch pinch and gesture interactions
- build draggable canvas drawing tools
- snap dragged elements to a grid
- unify touch and mouse event handling
- make SVG elements draggable

## When to choose
- you need fine-grained control over drag feedback rather than out-of-the-box movement
- you need multi-touch and simultaneous interactions in vanilla JS
- you must support older browsers like IE9+
- you want a framework-agnostic, standalone library with TypeScript types

## When to avoid
- you want built-in visual feedback, list reordering, or React/Vue components out of the box
- you need a full-featured UI framework rather than a focused interaction library
- your project already uses a framework with its own drag-and-drop ecosystem
