## What it is
Build scripts for compiling the JavaScriptCore (JSC) JavaScript engine for Android, distributed as the jsc-android npm package. It was created to let React Native (and other Android projects) use up-to-date JSC releases instead of Facebook's outdated 2014 build.

## Use cases
- build javascriptcore for android
- update jsc engine in react native android
- get a newer javascript engine for my android app
- package jsc as an aar for android
- use jsc-android in a non-react-native android project

## When to choose
- you need a recent JavaScriptCore version on Android for React Native or another native app
- you want to build JSC yourself with custom patches or configurations

## When to avoid
- your project uses Hermes or another JS engine already
- you only need to consume prebuilt jsc-android binaries rather than build them
- you target iOS, where JSC ships with the OS

## Facets
- artifact type: library
- maturity: maintenance
- function: build-tool, compiler, developer-tools
- domain: mobile-development, cross-platform, developer-tools
- platform: cli
- tags: javascriptcore, react-native, jsc-android, build-scripts, webkit, cmake, ndk, android, macos, linux
