## What it is
TwentyTwenty is a jQuery plugin that lets users compare two images with a draggable before/after slider. It supports horizontal and vertical orientations, custom labels, and touch/mouse interaction options.

## Use cases
- compare before and after images on a website
- add an image comparison slider to a page
- show photo retouching results side by side with a slider
- build a draggable before/after image viewer
- compare two versions of a screenshot interactively

## When to choose
- you already use jQuery and want a quick before/after image comparison widget
- you need touch and mouse support for image sliders on responsive sites

## When to avoid
- you use a modern framework like React or Vue without jQuery
- you need advanced image processing rather than a visual comparison slider

- maturity: maintenance
- function: ui-components, image-processing, animation
