如何用脚本把div转到下一行？

<style>
    .container {
        display: flex;
        flex-wrap: wrap;
    }
</style>

<div class="container">
    <div>Div 1</div>
    <div>Div 2</div>
    <div>Div 3</div>
</div>

<div id="container">
    <div>Div 1</div>
    <div>Div 2</div>
    <div id="divToMove">Div 3</div>
</div>

<script>
    var container = document.getElementById("container");
    var divToMove = document.getElementById("divToMove");
    container.appendChild(divToMove);
</script>
