    It creates one then destructs it.

    @ridecar2 ++ for ES6 then. By my feelings will stay with Python.

    Surely if the code works synchronously the variable do not swap but end the same. For example:
    a=1
    b=2
    a,b = b,a

    Gives us:

    a = b //a is now 1
    b = a //b is now also 1. Where's your 2?

    And my bad. It swaps objects assigned to those variables, not the variables themself. Memory wise that is.
