You can make it more explicit by renaming the import to something like "shell_exec". Tagged templates are already pretty common in TS projects for things like gql or sql queries.

I've either imported or created a sql template function that does exactly that... takes the parameters, forms a parameterized query against the database and returns the results back. Easy enough to add Typescript types that should match your expected results (though not enforced/checked) still helpful.
I know. My point was that the original text of the article gave no explanation next to that example as to how $ executes given string. So either there is some magic or the example was wrong. Author added explanation after my comment
tagged template does not cause execution of given string. tagged template is just a function and in this case it's simply a proxy for console.log() which also doesn't cause execution of given string.
so how does it get executed?
unless it was just an example and you are supposed to switch in $ from some third party library... which is another dependency in addition to deno... and which can be shai-huluded anytime or you may be offline and cannot install it when you run the script?
