Skookum JS, or sjs for short, is a JavaScript runtime focused on providing comprehensive POSIX APIs.

The motivation for this project comes from answering the question "how would a JavaScript runtime look like if there were no browsers?".

• Small footprint
• Ecmascript ES5/ES5.1 compliant, some features borrowed from Ecmascript ES6
• TypedArray and Buffer support
• Built-in regular expression engine
• Built-in Unicode support
• Tail call support
• Combined reference counting and mark-and-sweep garbage collection with finalization
• CommonJS-based module loading system
• Support for native modules written in C
• Rich standard library
• Binary name 25% shorter than Node

sjs would not have been possible without some other projects existing. Some served as a source of inspiration, some as a source of actual code, and the author would like to thank them all.

• Duktape: The engine that powers sjs. This project would not have been possible without Duktape. :hearteyes:
• Nodejs: World's most well known JavaScript runtime, definitely an inspiration.
• libuv: A lot of the cross-platform code was borrowed from here.
• Dukluv: Another JavaScript runtime combining Duktape with libuv.
• CPython: Python's canonical interpreter was an inspiration, specially for the standard library components.
