## What it is
jQuery Lazy is a lightweight, highly configurable lazy-loading plugin for jQuery and Zepto that delays loading of images, background images, and arbitrary content until it scrolls into view. It supports placeholders, retina displays, custom loaders, and callbacks to improve page speed and reduce traffic.

## Use cases
- lazy load images as user scrolls down a page
- defer background-image loading to speed up page load
- reduce bandwidth by only loading content in view
- lazy load content inside horizontally scrolling containers
- show placeholder images while content loads
- support retina images with lazy loading

## When to choose
- your site uses jQuery or Zepto and needs lazy loading of images or backgrounds
- you need broad legacy browser and old jQuery version compatibility
- you want configurable loaders, callbacks, and effects for deferred content

## When to avoid
- you use a modern framework with native loading='lazy' or IntersectionObserver-based solutions
- your project does not depend on jQuery or Zepto
- you need actively developed features or guaranteed long-term maintenance
