## What it is
AviatorScript is a high-performance, lightweight scripting language that runs on the JVM (including Android). It compiles scripts to JVM bytecode via ASM, supports closures, functional programming, big integers and high-precision decimals, and can be embedded in Java applications as a safe expression evaluator or full scripting language.

## Use cases
- evaluate dynamic expressions in a Java application
- build a rule engine for business rule evaluation
- compute formulas at runtime
- embed a sandboxed scripting language in the JVM
- run ETL transformations over collections
- control application behavior with dynamic scripts

## When to choose
- you need fast, lightweight expression or formula evaluation on the JVM
- you want an embeddable scripting language with sandboxing and execution timeouts
- you need a rule engine DSL that Java can call and be called from
- you need scripting support on Android or non-standard Java platforms

## When to avoid
- you need a general-purpose standalone language with a large ecosystem and libraries
- you need deep native integration beyond Java method calls
- you require a language with extensive third-party tooling and IDE support

## Facets
- artifact type: library
- maturity: stable
- function: interpreter, programming-language, compiler
- domain: programming-languages, developer-tools, backend
- platform: jvm, cross-platform
- tags: expression-evaluator, scripting-language, rule-engine, formula-evaluation, sandbox, asm-bytecode, android
