There is no "one thing", there's many things, the top of the list being:

- packages in workspaces can be used as dependencies without compilation (node's type stripping doesn't support this)

- a good permissions model for limiting access to system fs, net, etc.

- native WebGPU support (including building a windowed app without a web view)

- desktop gui builds that allow using Chromium embedded or WebView

- built-in linter, benchmark, coverage, etc.
