    Java Script Memory Management Questions

    Hi,

    I'm trying to find out how JavaScript manages its memory. In
    particular when using the 'new' operator to create an object is it
    necessary to explicitly delete this object (before it moves out of scope,
    like c++) or does JavaScript clean this up automatically?

    What about string varaible which uses concatenation extensively?

    Thanks.

    George

      Javascript has it's own garbage collection mechanism. You do not need
      to delete variables created with new. (I dont think you can)

      Strings follow the same model.
