Can't get my word randomizer script to loop properly

I'm trying to get this script to run, than end on the word Awesome. and then loop again/repeat.

Here's the JS

var i, word, rnd, words, fadeSpeed, timer;

words = ['respected​.', 'essential.', 'tactical.', 'effortless.', 'credible.', 'smart.', 'engaging.', 'focused.', 'effective.', 'clear.', 'relevant.', 'strategic.', 'trusted.', 'compelling.', 'admired.', 'inspiring.', 'cogent.', 'impactful.', 'valued.'];

fadeSpeed = 500;
timer = 2000;

for (i = 0; i < 20; i++) {
    if (i === 19) {
        word = 'awesome.';
        rnd = Math.floor(Math.random() * words.length);
        word = words[rnd];
        words.splice(rnd, 1);
    } else {
        rnd = Math.floor(Math.random() * words.length);
        word = words[rnd];
        words.splice(rnd, 1);
    }

    (function(word) {
        $('h1.random em').fadeOut(fadeSpeed, function() {
                $(this).html(word);
            })
            .slideDown('slow')
            .delay(timer)
            .fadeIn(fadeSpeed);
    })(word);
}
