What is the difference between node.nextSibling and ChildNode.nextElementSibling?
提问by Ani
<div id="div-01">Here is div-01</div>
<div id="div-02">Here is div-02</div>
<div id="div-01">Here is div-01</div>
<div id="div-02">Here is div-02</div>
Aren't they the same thing ?
他们不是一回事吗？
Both returning the immediately followed node. I read a lot of articles but seems to me like the same thing, but can't figure where to use one versus other ?
两者都返回紧随其后的节点。我阅读了很多文章，但在我看来似乎是同一件事，但不知道在哪里使用一个和另一个？

nextElementSiblingalways returns an element. nextSiblingcan return any kind of node. They are the same for your example, but different in other cases, e.g.:
nextElementSibling总是返回一个元素。 nextSibling可以返回任何类型的节点。它们与您的示例相同，但在其他情况下不同，例如：
<p><span id="span-01">Here is span-01</span>
Some text at the top level
<span id="span-02">Here is span-02</span></p>
In this case, document.getElementById('span-01').nextElementSiblingis span-02, but document.getElementById('span-01').nextSiblingis the text node containing "Some text at the top level" (or, as pointed out by @Manngo in the comments, the whitespace that separates that text from the element above -- it seems some browsers put whitespace between elements and non-whitespace nodes into separate nodes, while others combine it with the rest of the text).
在这种情况下，document.getElementById('span-01').nextElementSiblingis span-02，但是document.getElementById('span-01').nextSibling是包含“顶层的一些文本”的文本节点（或者，正如@Manngo 在评论中指出的那样，将文本与上面的元素分开的空格——似乎有些浏览器把元素和非空白节点之间的空白转换为单独的节点，而其他节点则将其与文本的其余部分结合起来）。
