// Now we can get back to that item we just pushed via .child().

}

var testRef = new Firebase("https://example.firebaseIO.com/");
var newRef = pushSomething(testRef);
// Later... should popup an alert that says "null" (No Error).

}
/* for testing: */
var name = 'me';

var nameRef = new Firebase('https://examplefirebase.firebaseio.com/RemoveTest');
nameRef.child('test').set('anothertest'); // writing data as list (adds node directly under root)
nameRef.child('test').push('moretesting'); // using child instead of set (generated unique child name) (adds "moretesting" to uniquely named child node of test child node of root)
nameRef.push({name: name, text: text}); // automates generation of unique child names (adds uniquely named node under root with two child nodes "me" and "something")
nameRef.set({name: name, text: text}); // object (overwrote all child nodes of root, adds "me" and "something")
nameRef.update({name: name, text: text}); // writing multiple children without overwriting other data
$('#remove').on('click', function(){
console.log('button clicked');
event.preventDefault();
nameRef.child('test').remove(); // this removes the parent of test (RemoveTest)
nameRef.child('name').remove(); // this removes "name:'me'" from root (RemoveTest)
