    Default String Concatination

    String Concatination

    In the source code i came across a couple of string concatinations using +.
    It would be nice if these are changed to using the array.join() as we gain much better performace.

    brian.moeskau is an unknown quantity at this point



    Actually, this is a common misperception. Array.join() is always more efficient AFTER a certain point, but for a few values, the concatenation operator is actually faster (and more convenient of course):


    When the number of values being concatenated is small enough the concatenation operator still wins. The cross-over point is not entirely deterministic, but exists somewhere in the neighborhood of 7-13 values. For larger strings the count may be much smaller.
