## What it is
A small, fast JavaScript library for delegated event listeners in the browser. It lets you bind event handlers with CSS selectors so they work for dynamically added elements without re-binding.

## Use cases
- handle click events on dynamically added DOM elements
- attach event listeners with CSS selector matching
- avoid re-binding listeners after DOM updates
- dispatch and listen for custom events on elements
- replace jQuery-style event delegation in vanilla JS

## When to choose
- you need event delegation without a full framework
- your page content changes dynamically and listeners must persist
- you want a tiny, dependency-free browser library

## When to avoid
- you use a framework like React or Vue with its own event system
- you need server-side or Node.js event handling
- you need complex event state management

## Facets
- artifact type: library
- maturity: maintenance
- function: frontend-framework
- domain: web-development, frontend, developer-tools
- platform: browser
- tags: event-delegation, dom-events, vanilla-js, micro-library, zero-dependencies, event-handling, dom, javascript
