When comparing += and Array.join for building a string it might give a more precise picture of the actual cost of building a string if the constructed string is being used afterwards. E.g. include the time used to run a simple RegExp on the string. The string tree built using += will most likely need to be converted into a flat string before complex operations (like RegExp) can be performed on it.
