Remove all child elements in Titanium

app.js

function removeAllChildren(viewObject){
    //copy array of child object references because view's "children" property is live collection of child object references
    var children = viewObject.children.slice(0);
 
    for (var i = 0; i < children.length; ++i) {
        viewObject.remove(children[i]);
    }
}

Nice!
