I don't think the speed matters persa, what annoys me is when starting a node project I have to install typescript, jest, eslint (any plugins) then whatever dependences I am using and then set up a tsconfig and what every else also needs a config file.
In deno you can just open your ide, add some imports to the import map and you're ready to code.
This is it for me too... with Deno, I can write a fully contained one-off script with a shebang and use it for general shell scripting.. with node, it was never that simple. Though having to use the `#!/usr/bin/env -S -- deno run ...` is still a little more awkward.
Direct imports that the runtime caches for you, vs node_modules is way easier to deal with most of the time.
