## What it is
A lightweight, dependency-free vanilla JavaScript plugin that animates scrolling to anchor links on a page. It is now deprecated in favor of the native CSS `scroll-behavior: smooth` property.

## Use cases
- animate scrolling to anchor links
- smooth scroll navigation on a static website
- add smooth scrolling without jQuery or dependencies
- scroll to section with easing options
- implement one-page navigation with animated scrolling

## When to choose
- you must support very old browsers that lack CSS scroll-behavior support
- you need easing or speed controls the native CSS approach doesn't offer
- you're maintaining a legacy site already using the plugin

## When to avoid
- starting a new project - use the native CSS `scroll-behavior: smooth` instead
- you need cross-page anchor scrolling, which the plugin doesn't support
- you want actively maintained software with bug fixes

## Facets
- artifact type: library
- maturity: abandoned
- function: animation, ui-components
- domain: web-development, frontend
- platform: browser
- tags: vanilla-js, anchor-links, smooth-scrolling, no-dependencies, deprecated, javascript
