javascript check if value has at least 2 or more words

Question

I have a field that you enter your name in and submit it. I would like the receive peoples first and last names and to do this i need to check if the value contains at least 2 words. This is what I am using right now but it doesn't seem to work.

function validateNameNumber(name) {
    var NAME = name.value;
    var matches = NAME.match(/\b[^\d\s]+\b/g);
    if (matches && matches.length >= 2) {
        //two or more words
        return true;
    } else {
        //not enough words
        return false;
    }
}
