## What it is
A concise overview document of ECMAScript 6 (ES2015) language features with short code examples for each feature such as arrows, classes, template strings, destructuring, generators, and promises. It is a reference/learning resource rather than a software library or tool.

## Use cases
- learn what's new in es6 javascript
- quick reference for es6 syntax examples
- understand arrow functions classes and template literals
- overview of ecmascript 2015 features for a team
- brush up on javascript generators and promises
- find code samples for destructuring and spread operators

## When to choose
- you want a short, example-driven summary of ES6 features
- you are teaching or onboarding developers on modern JavaScript basics
- you need a quick lookup of ES6 syntax without reading the full spec

## When to avoid
- you need exhaustive or up-to-date language documentation (use MDN or the ECMAScript spec)
- you need a runnable library, transpiler, or tool
- you need features introduced after ES6/ES2015

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation
- domain: programming-languages, web-development, tutorials
- platform: browser, cross-platform
- tags: javascript, es6, ecmascript-2015, language-features, reference-guide, cheatsheet, nodejs
