• A method cannot be passed as a parameter in JS:

    (arg, methodName) => {
        const whatever = calc(arg);
        whatever.methodName(); // <-- This won't work.
    }

Reminder:

• You can directly modify a CSS attribute:

    const selector = document.querySelector('class|id|tag'); 
    selector.style.cssAttribute = `value`;
    // e.g: hand('second').style.transform = `rotate(${...}deg)`;
