## What it is
Zepto.js is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API, designed to be a tiny (~5-10k gzipped) modular alternative to jQuery. It provides core DOM manipulation, event handling, Ajax, form serialization, and optional modules for effects, touch events, and detection.

## Use cases
- replace jQuery with a smaller library in a mobile web app
- manipulate the DOM with a familiar jQuery-style API
- make Ajax requests and handle JSONP in a lightweight page
- add touch event handling to a mobile website
- build a fast-loading page with minimal JavaScript payload
- serialize and submit web forms with JavaScript

## When to choose
- you already know jQuery and want a much smaller footprint for modern browsers
- you are building a mobile-focused site where download size matters
- you only need core DOM, events, and Ajax functionality

## When to avoid
- you need full jQuery plugin ecosystem compatibility or 100% jQuery coverage
- you must support legacy browsers like IE9 and below
- you are starting a new project where a modern framework or native DOM APIs would be a better fit

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, http-client, animation, form-handling
- domain: web-development, frontend, developer-tools
- platform: browser, cross-platform
