I guess there’s no accounting for taste!

It would be nice to leverage this from the command line.

What JavaScript needs to make that “triangle()” function readable is a decent exponentation operator, not white-space sensitivity.

sub triangle($a, $b) {
($a ** 2 + $b ** 2) ** 0.5
}

For the second one the ternary operator and a loop statement that doesn’t suck will suffice:

for 0..5 -> $i {
document.getElementById(“#el” ~ i).innerHTML = ($count % 2) ?? “World” !! “Hello”
}

The JavaScript ternary operator is flawed and that makes it hard to read, the (? :) syntax is confusing, however, if you put (?? !!) its pretty easy to understand because (?) is always associated with true booleans and (!) is always associated with false ones.
