## What it is
Jump.js is a small JavaScript library for smooth scrolling to elements or pixel offsets in the browser. It exposes a singleton function with configurable duration, easing, offset, callback, and accessibility options.

## Use cases
- smooth scroll to an element on click
- animate scrolling to anchor links
- scroll page by a number of pixels
- add easing to page scrolling
- scroll with offset for fixed headers

## When to choose
- you need a tiny, dependency-free smooth scrolling helper
- you want configurable duration and easing for scroll animations
- your project already uses an ES6 module bundler

## When to avoid
- you need scroll-spy or scroll position tracking
- you want CSS-only scroll-behavior without JavaScript
- your project cannot run a modern build pipeline

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components
- domain: frontend, web-development
- platform: browser
- tags: smooth-scrolling, scroll-animation, es6, npm, nodejs, javascript
