I don't know how I feel about this.

It is _technically_ cool but I feel like this existing is a definite step backwards with regards to Node.js' lack of modern web APIs.

Software like this relieves pressure in moving from Node.js specific APIs towards standardised web APIs and in addition to that itself boasts about portability by ignoring modern features too. From their WebContainer vs Nodebox FAQ:

    Nodebox runs on any browser because it was built from the ground up with cross-browser support in mind, avoiding modern features like SharedArrayBuffer."

So now we've got an escape hatch for Node.js not having to implement modern APIs because software like this implements its runtime for the browser, and also this same software removes pressure on browser vendors bringing their implementations up to webstandard specifications by "... avoiding modern features".

While this is _technically_ cool I feel like it's a lose-lose for the overall ecosystem.
