For some performance reasons, I am trying to find a way to select only sibling nodes of the selected node.

For example,

<div id="outer">
  <div id="inner1"></div>
  <div id="inner2"></div>
  <div id="inner3"></div>
  <div id="inner4"></div>
</div>

If I selected inner1 node, is there a way for me to access its siblings, inner2-4 nodes?

javascript html dom siblings
