The order of execution is defined as follows:
1. first, we execute all the py-script tag in order
2. then, we start all the tasks which were scheduled with create_task
Note that tasks are started *AFTER* all py-script tags have been
executed. That's why the console.log() inside mytask1 and mytask2 are
executed after e.g. js.console.log("6").
