I didn't know, but apparently you can execute a function in JS without parentheses using upticks (`), e.g:

  functionName`param`

and whatever is inside of the upticks get sent to the function as an array. It's also what Bun is doing with it's $ (dollar sign) function for executing shell commands. There's so much weird syntax magic in JS.

These are called "tagged templates": https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...

Tagged templates are really cool. They are a reasonably simple extension of template strings, which allow constructing strings very easily by allowing arbitrary code to be put inside a ${} block inside of template strings (ones that begin and end with backticks ` instead of single or double quotes).

So if you think about it template strings are like a tagged template who's function just calls .toString() and concatenates each argument it is given. There are some really nice safe sql libraries that use this for constructing queries. They are useful basically anywhere you might want string interpolation and a bit of type safety, or special handling of different types.

Lit Element is also a very clever usage of tagged templates.

I just wish they had something like pythons triple quotes or here docs or c++ r strings. A single backtick makes it hard to use backticks inside the string

I especially like recent perls' support for <<~ as a << that strips indentation so you can keep your HERE doc contents indented along with the rest of the code.

(and everybody with a HERE doc implementation that doesn't have that yet should absolutely implement it, people who can't stand perl deserve access to that feature too ;)

Ah! There's a lot more to this than just executing a mere function it seems. Consider me educated!
