## What it is
Anko is a scriptable interpreter written in Go that provides its own JavaScript-like scripting language. It can be embedded in Go applications to run user-defined scripts or used as a standalone command-line interpreter.

## Use cases
- embed a scripting language in my Go application
- let users write custom scripts to extend my Go program
- run dynamic configuration or automation scripts from Go
- evaluate simple expressions or logic at runtime in Go
- execute .ank script files from the command line
- add a lightweight DSL interpreter to my Go service

## When to choose
- you need an embeddable scripting language in a Go application
- you want a simple, Go-like syntax for user scripts
- you need to expose Go functions to a sandboxed script environment

## When to avoid
- you need a mature, widely-adopted scripting language with a large ecosystem
- you need high-performance execution of complex scripts
- you need strict stability guarantees, since the master branch API and language may change

## Facets
- artifact type: library
- maturity: active
- function: interpreter, programming-language
- domain: programming-languages, developer-tools
- platform: go, cross-platform, cli
- tags: scripting-language, embedded-interpreter, golang-library, scripting, automation
