Question

How do I write a jQuery function so that it returns a value that I can access outside the function? I did something like this but when I tried to access it outside the function, it says “undefined”:

$(document).ready(function(){
    function add(y, z) {
        $('p').click(function() {
            x = y + z;
            console.log(x); // shows 3
            return x;
        });     
    }

    var sum = add(1, 2);

    console.log(sum); // shows "undefined"
});

This should work. Not sure why you added the click event there

$(document).ready(function(){
    function add(y, z) {
        x = y + z;
        console.log(x); // shows 3
        return x;
    }
    var sum = add(1, 2);

    console.log(sum); 
});
