ux-wise, you can achieve the same with a helper-function debugInline (used in this real-world example);

inline-debugging becomes trivial as follows:

#!/bin/sh

node -e '
// this inline-debugger can be safely copy-pasted into any script
// init debugInline
if (!globalThis.debugInline) {
    let consoleError;
    consoleError = console.error;
    globalThis.debugInline = function (...argList) {
    /*
     * this function will both print <argList> to stderr and
     * return <argList>[0]
     */
        consoleError("\n\ndebugInline");
        consoleError(...argList);
        consoleError("\n");
        return argList[0];
    };
}

function randInt(min, max) {
    // return Math.floor(
    //     min +
    //     Math.random() * (max - min)
    // );
    return Math.floor(
        debugInline(  min, "min"  ) +
        debugInline(  Math.random() * (max - min), "random*scale ")
    );
}
randInt(0, 10);
