[Solved] How frequently to write to flash without damage?

Hi,

I am developing a timer widget.
As this only counts the seconds when it is loaded, I am storing the current seconds to flash.
This way it can pick up where it left when the widget is loaded again.

const storage = require('Storage');
storage.write('chronowid.json', settings);

Currently I am doing this every second, but could this hurt the flash memory?

Thanks
