Will output in the console what the stack is at the moment this is called.

logStack.js

// nb [int] the number of line to get from the stack
function logStack (nb) {
    try {
        throw new Error();
    } catch (e) {
        var stack = e.stack.match(/(https?:\/\/[\w.:0-9\/]+)/g);
        if (nb === undefined) {
            nb = stack.length - 2;
        }
        console.log(
            '- Stack(' + nb + ') :\n       ' +
                _.first(_.last(stack, stack.length - 2), nb)
                .join('\n       ')
        );
    }
}
