Supported JS Language Reference

Is it documented which JavaScript commands, directives, standard libraries, etc are supported by Mongoose OS? For example, Uint8Array() doesn’t appear to be. So is there guidance on what is or isn’t supported?

mJS: Restricted JavaScript engine
====================================

[![License](https://img.shields.io/badge/license-GPL_2-green.svg)](https://github.com/cesanta/mjs/blob/master/LICENSE)

# Overview

mJS is designed for microcontrollers with limited resources. Main design
goals are: small footprint and simple C/C++ interoperability. mJS
implements a strict subset of ES6 (JavaScript version 6):

- Any valid mJS code is a valid ES6 code.
- Any valid ES6 code is not necessarily a valid mJS code.

On 32-bit ARM mJS engine takes about 50k of flash memory, and less than 1k
of RAM (see [intro article](http://goo.gl/zJYyWF)).
mJS is part of [MongooseOS](https://mongoose-os.com), 
where it enables scripting for IoT devices.
