What is it?
How does it work?
How much RAM and ROM does it consume?
Date etc, but MetalScript treats these in a way that does not consume any resources of themselves, similarly to how the C++ standard template library does not consume any resources of itself. You only pay for what you use and how you use it.
MetalScript supports most features of ES6. It does not support
eval and relatives of
eval, since MetalScript is a compiler and does not provide the capability of executing dynamic code at runtime.
MetalScript is still under development
The MetalScript project is under development. The above points describe the design and intention of the project, and not measurable facts (yet).
