    $$var uses the value of the variable whose name is the value of $var.
    It means $$var is known as reference variable where as $var is normal variable.

    $var uses the value of the variable whose name is the value of $var.
    It means $$var is known as reference variable where as $var is normal variable.
    It allows you to have a “variable’s variable” – the program can create the variable name the same way it can create any other string.
