The way I understood it data is not supposed to presist between ticks, but it seems to do just that for a short amount of time.

Example code:

let debug = {
    counter: 0,
    run () {
        console.log(debug.counter);
        debug.counter++;
    },
};

module.exports = debug;

Running debug.run() in the main loop gives me 0, then 1, then 2, then 3 and so on.

Why is this happening?
