How exactly will the new runtime fix the habit of Javascript developers to pull-in millions of dependencies?

Makes me look forward to this more https://romejs.dev/ since one of the ideas is that it will have no third party dependencies...

What is this exactly? The website is a bit unclear.

Deno is much like node (uses the V8 engine, does not require a browser) and was created by the man who created node.

I was wrong about what this was I have edited this comment

Why would a Rust wrapper around the C++ project that is V8, which implements a garbage-collected programming language and environment, "use less ram" just by virtue of some parts of it being written in Rust?
