## What it is
A set of JavaScript koans (test-driven learning exercises) based on the Ruby Koans, where learners fix failing Jasmine tests to progress. It teaches JavaScript syntax and functional programming concepts through iterative error fixing in the browser.

## Use cases
- learn javascript through exercises
- practice fixing failing tests
- beginner javascript tutorial
- learn functional programming in javascript
- self-study javascript fundamentals
- teach javascript with test-driven exercises

## When to choose
- you want a hands-on, test-driven way to learn JavaScript basics
- you prefer fixing errors over reading documentation
- you want a browser-based exercise with no setup

## When to avoid
- you need a comprehensive modern JavaScript course covering ES6+ features
- you want production tooling rather than a learning exercise
- you need an actively developed curriculum

## Facets

- maturity: maintenance
- function: testing, developer-tools
- domain: programming-languages, tutorials, education, developer-tools
