## What it is
MooTools Core is a classic JavaScript utility framework providing an elegant class-based OOP system, DOM manipulation, selectors, events, and Ajax (Request) APIs for browser development. This repository contains the core framework source, build tooling (Grunt), and test specs for contributors.

## Use cases
- manipulate DOM elements and query selectors in the browser
- attach and manage event handlers on elements
- make Ajax requests with a class-based Request API
- write object-oriented JavaScript with a Class system
- animate elements with Fx transitions
- maintain legacy web apps built on MooTools

## When to choose
- maintaining or extending an existing MooTools-based codebase
- you need a lightweight, class-based vanilla JS utility layer without a virtual DOM
- you want well-documented, extensible browser utilities with MIT licensing

## When to avoid
- starting a new modern web project - React, Vue, or native DOM APIs are better supported
- you need server-side rendering or a component ecosystem
- you require active community development - the project is largely in maintenance mode

## Facets
- artifact type: library

- function: ui-components, http-client, animation, state-management, developer-tools
- domain: web-development, frontend
