## What it is
A Ruby gem that embeds the V8 JavaScript interpreter into Ruby, letting Ruby code evaluate JavaScript, expose Ruby objects to JS, and call JS functions. The project is officially unmaintained, with mini_racer recommended as its successor.

## Use cases
- evaluate javascript from ruby
- run javascript inside a ruby application
- embed v8 in ruby
- execute js templates from ruby
- call javascript functions from ruby code

## When to choose
- you are stuck maintaining a legacy codebase that already depends on therubyracer and v8 3.16

## When to avoid
- starting any new project - use mini_racer instead
- you need a modern V8/Node engine
- you want a maintained dependency

## Facets
- artifact type: library
- maturity: abandoned
- function: interpreter, parser, developer-tools
- domain: programming-languages, developer-tools, web-development
- platform: ruby, cross-platform
- tags: v8, javascript-embedding, ruby-gem, unmaintained, libv8
