Extjs Treepanel - How to delete root of a tree

I have a tree panel with local data like

 root: {
            text: 'root',
            children: [
                { text: "child"
                  leaf: true
                }]
 ....
}

first: I want to delete root of tree. I try below code but that not working for root. However that work for another node (node.remove(true))

tree.getRootNode().remove(true);

second: I want to remove all tree (i think this like remove root?)
How can i do that thanks :)

Stated in Ext doc, the Ext.dataNodeInterface.remove:

Removes this node from its parent

Root node has no parent, so remove won't work. However, to remove the whole tree from treepanel, you can try:

treepanel.setRootNode(null);

I have created a plunk to demonstrate a few examples you might be interested in.
