## What it is
A collection of JavaScript polyfills and shims covering ECMAScript standards and web browser APIs, organized into files matching web specifications. It lets developers write future-looking code using modern platform APIs while filling gaps in older browsers.

## Use cases
- add es6 features to older browsers
- polyfill fetch and xhr in legacy browsers
- support new dom apis in internet explorer
- write future-looking javascript with fallbacks
- shim missing web platform apis
- bundle browser compatibility polyfills into one script

## When to choose
- you need lightweight per-spec polyfill files you can pick from
- you want a single bundled script covering ES5 through ES2017 plus common web APIs
- you accept approximate, not 100% spec-compliant, behavior

## When to avoid
- you need fully spec-compliant polyfill behavior
- you target only modern evergreen browsers with no legacy support
- you need a maintained Node.js module - this is browser script distribution only

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, developer-tools
- domain: web-development, frontend, cross-platform
- platform: browser
- tags: polyfills, shims, ecmascript, web-apis, browser-compatibility, es5, es6, dom, javascript
