## What it is
The source of es6-features.org, a website providing an overview of ECMAScript 6 language features with side-by-side comparisons to their ECMAScript 5 equivalents. It serves as a bookmarkable reference covering constants, arrow functions, classes, modules, promises, generators, and more.

## Use cases
- learn what's new in ES6
- compare ES6 syntax with ES5 equivalents
- find a quick reference for JavaScript arrow functions or destructuring
- share bookmarkable links to specific ECMAScript 6 features
- look up examples of ES6 classes, promises, or generators
- onboard a team to modern JavaScript syntax

## When to choose
- you want a concise visual overview of ES6 features with ES5 comparisons
- you need a quick reference to link to when explaining ES6 syntax
- you are learning modern JavaScript and want categorized code examples

## When to avoid
- you need up-to-date coverage of ES2020+ features beyond ES6
- you need detailed browser compatibility data (use kangax's compat-table instead)
- you need the official language specification or a tutorial with exercises
