why is x undefined in my nested for loop

function createDeck() {
    var suites = ['♠︎', '♣︎', '♥︎', '♦︎'];
    var ranks = ['Ace', 'King', 'Queen', 'Jack', '10', '9', '8', '7', '6', '5', '4', '3', '2'];
    var deck = [];

    // add your code below here:
    for (i = 0; i < suites.length; i++) {
        for (x = 0; x < ranks.length; i++) { // I've ran it through the debugger and it says x underfined 
            console.log(ranks[x])

        }


    }

}





createDeck();
