## Definition and Usage

The isSameNode() method checks if two nodes are the same node.

The isSameNode() method returns true if the two nodes are the same node, otherwise false.

Tip: Use the isEqualNode() method to check if two nodes are equal, but not necessarily the same node.

## Browser Support

The isSameNode() method is supported in all major browsers, except Firefox.

Note: Firefox stopped supported this method as of version 10, because the method has been deprecated in the DOM version 4. Instead, you should use === to compare if two nodes are the same.

Note: Internet Explorer 8 and earlier does not support this method.
