## What it is
A tiny dependency-free JavaScript library that prevents iOS Safari's rubber-band bounce effect in full-screen mobile webapps by selectively calling preventDefault on touchmove events. It is now largely superseded by the native CSS overscroll-behavior property.

## Use cases
- stop ios webapp viewport from bouncing when scrolling
- prevent rubber band scrolling in mobile safari
- fix scroll bounce in full-screen mobile web app
- disable overscroll bounce on ios
- make inner scrollable lists work without page bounce on iphone

## When to choose
- you must support older iOS browsers lacking overscroll-behavior support
- you want a zero-dependency drop-in script for legacy mobile webviews
- you need programmatic enable/disable of bounce prevention

## When to avoid
- your target browsers support the CSS overscroll-behavior property - just use that instead
- you are building a native iOS app rather than a web app
- you need a maintained solution with active development

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, middleware
- domain: web-development, frontend, mobile-development
- platform: browser
