This is probably not the most interesting of intriguing features in the stack but I would love to see Deno support. Deno looks pretty promising, and it might even reduce the amount of storage it takes for dependencies since it uses a different approach compared to NPM.
For the people who don’t know Deno, it’s kinda like a more modern version of NodeJS written by the guy who made the OG Node JS. It just hit version 1.0 today, so there aren’t a bunch of 3rd party packages.
