I don’t think you have read the current Version. Hereby the first two paragraphs:

“ Rome is an experimental JavaScript toolchain. It includes a compiler, linter, formatter, bundler, testing framework and more. It aims to be a comprehensive tool for anything related to the processing of JavaScript source code.

Rome is not a collection of existing tools. All components are custom and use no third-party dependencies.”

What does it compile JavaScript to though? WebAssembly or native code?

It looks like it's compiling TypeScript/Flow and newer JS features into more standard JS. Part transpiling.

Compiler here probably means transpiler. Like Babel. Supporting new ECMAScript stuff, transpiling it to ES3/ES5 or whatever, so you can use it in IE6, or on NodeJS 8.

> Compiler here probably means transpiler.

A transpiler is a type of compiler, so it's fine to just call it a "compiler".

'Transpiler' adds useful extra information and context though. It's like it's fine to just say 'animal' but it's a bit more useful with more information to say 'cow'.
