如何在Div中动态添加段落？

<div id="myDiv"></div>

var div = document.getElementById("myDiv");

var paragraph = document.createElement("p");

paragraph.innerHTML = "这是一个新的段落。";

div.appendChild(paragraph);

<div id="myDiv"></div>

<script>
    var div = document.getElementById("myDiv");
    var paragraph = document.createElement("p");
    paragraph.innerHTML = "这是一个新的段落。";
    div.appendChild(paragraph);
</script>
