function longestWord(string) {

    var str = string.split( );

    var longest = 0;

    var word = null;

    for (var i = 0; i < str.length - 1; i++) {

        if (longest < str[i].length) {

            longest = str[i].length;

            word = str[i];

        }

    }

    return word;

}

When I call longestWord(Pride and Prejudice), it returns 'Pride' and not 'Prejudice' which is the longest word... why? I checked some other similar questions, but the solutions looked a lot like my code.
