## What it is
iScroll is a high-performance, dependency-free JavaScript library (~4kb) that adds smooth scrolling, zooming, panning, infinite scrolling, parallax, and carousels to web pages. It works across desktop, mobile, and smart TV browsers, including legacy platforms, and ships in multiple optimized variants (lite, probe, zoom, infinite).

## Use cases
- add smooth momentum scrolling to a mobile web page
- implement infinite scrolling for long lists on mobile
- build a touch-friendly carousel in vanilla JavaScript
- add pinch zoom to a scrollable area
- support smooth scrolling on old Android browsers and legacy devices
- track scroll position continuously during momentum
- create parallax scrolling effects

## When to choose
- you need consistent, smooth scrolling behavior across old and new browsers and devices
- you want a tiny, dependency-free scroller with fine-grained control over position, easing, and events
- you need features native scrolling lacks, like snap, infinite lists, or zoom

## When to avoid
- your target browsers support modern native scrolling and CSS scroll features, which are lighter and maintained
- you need a component library with maintained updates - the project has had no release since late 2018
- you are building with a modern framework that already provides scrolling solutions
