Deno is on my list of tools to play with. It's sandboxing capabilities are the main selling point for me because it will allow executing semi-trusted/un-trusted code on private data sets. If I know that the code can't access the network or do anything fancy with the file system then I can treat the untrusted code as a pure function and know that the output will only depend on the input. This is a very desirable property and I'm looking forward to the type of code and data sharing it will enable.

Sandboxing has been possible for many years before Deno. Running untrusted code is not popular for good reasons.

I'm aware but Deno allows more programmers to take advantage of those capabilities in a way that will make sense to them which will lead to more and better applications. I think every programmer intuitively understands what network and filesystem access means. Deno has made sandboxing much more approachable and since those capabilities are front and center instead of some hidden feature more people will take advantage of them to structure their applications.
