Create and append/remove versus display:block/display:none (improved)

By writing javascript web applications It is often common the need to show or hide elements like a div according to the user actions. Is it better to do this by creating and appending the node when it is needed or to create the node on the application start and then just display or hide it? This benchmark is a performance test of this particular use case. In this version, the createAppendDiv was isolated from operations that can be done once, so the test executes just the operations that are really essencial for the test case.
