"Let's build a runtime"
proceeds to install prebuilt runtime libraries 😶

Yo dawg, I heard you like building frameworks, so we put a framework inside a framework so you can build a framework while you use a framework.

is this a runtime, or is it a rust program using deno as a runtime?

Imagine showing this to doctors while they kindly accompany you to your ward nodding “yes, sure mate, a-ha”

The new running joke is "you have a working library in Javascript? lets write it in rust"

If this series ever gets updated it might be interesting to see how to pass existing data from from Rust to JS and back

Hmm the core api has changed a lot since the blog post was written (July 2022) so the code doesn't work anymore!

Aghh.. now u have unlocked this new domain of writing infinite amount of runtimes to the JS community.
Now, we've to suffer the consequences.

Wouldn't a dedicated scripting engine be a better job for the task than a copy of V8? Especially since v8 is absolutely massive, and plugins are not the hot code path anyway (or they shouldn't be at least). IMO, an embeddable scripting language like starlark or even just a copy of QuickJS would work much better than v8 (and also it would not be a 50 megabyte codesize increase, which is also fun)

Is there any reason to make your own runtime instead of using node or deno directly?

this seems insanely powerful...whatever it meant to be a pc developer probably applies even less now
