In the version 1.6 of Deno runtime come with a new tool,
deno compile. This new feature is used to build a completely standalone binary to your script, it means it does not need to have the Deno installed on your PC to run your code.
With the code above, it is possible to try this new feature and it will generate a bin file ready to run.
deno compile --unstable https://firstname.lastname@example.org/examples/welcome.ts
After that, it just runs the output file
./welcome Welcome to Deno 🦕
Unfortunately, this feature is not full working, and it has some issues to fix in the future, further information can be found here: https://deno.land/posts/v1.6#codedeno-compilecode-building-self-contained-standalone-binaries
