Convert DEVONthink Sheet to Markdown script?

Which reminds me, on the choice of which language to reach for when a task arises, that this morning I wanted a function that would give a true/false value in exchange for a Regex pattern and a string:

regexTest :: RegexPattern -> String -> Bool

My choices were either AppleScript:

use framework "Foundation" -- "OS X" Yosemite onwards, for NSRegularExpression

-- regexTest :: RegexPattern -> String -> Bool
on regexTest(strRegex, str)
    set ca to current application
    set oString to ca's NSString's stringWithString:str
    ((ca's NSRegularExpression's regularExpressionWithPattern:strRegex ¬
        options:((ca's NSRegularExpressionAnchorsMatchLines as integer)) ¬
        |error|:(missing value))'s firstMatchInString:oString options:0 ¬
        range:{location:0, |length|:oString's |length|()}) is not missing value
end regexTest


regexTest("\\s", tab)

-- result: true

or JavaScript for Automation:

    // regexTest :: RegexPattern -> String -> Bool
    function regexTest (rgx, s) {
        return rgx.test(s);
    }
    

    regexTest(/\s/, '\t');

    // result: true

AppleScript seemed a bit hard for a person of my advancing years …
