Keeping this as a draft until #47 is resolved.

Why would this be needed if we support nodejs?

[Arxcis]

@Avokadoen Hah! Outrageous. They are completely different languages. Instead of having a main.js file, you would have a main.ts file for example! 😆 (joking)

[Arxcis]

Instead of writing no-de you write de-no !! The opposite 😝

The list goes on.... (no it doesn't)

[Arxcis]

Jokes aside. I really want to use this, instead of nodejs, that is why I am adding it. This also allows us to learn more about the minute differences between these two run-times, which I think is worth exploring 😄 as deno markets itself as a "better nodejs".

[Avokadoen]

It's worth noting that ts targets js, so you can run ts as long as you have node and the typescript transpiler. I think deno looks like an amazing project, so this definitely adds value to the repo!
