Name still returns

var userName = function userName(){

        var name = prompt("What is your name");
        if(name === "David")
                alert("Please choose another name");
                name = prompt("What is your name");

                return name;

};

var result = userName(); document.write(result);

I don't think having to write name = prompt("What is your name"); twice is correct. Im sure there is an easier way for this work ....

Hi David,

A better way to ask the name until the name is not equal as "David" would be using the do-while loop.

Here is the function using it:

var userName = function userName() {
    do {
        name = prompt("What is your name");
        if(name === "David") {
            alert("Please choose another name");
        }
    } while (name === "David");
    return name;
};

In this case the content of the do block will be repeated every time the while condition is true.
