Dinner Shuffler - Randomly select dinner for every day of the week

espenrog94

Hi,
Made a module for displaying a random list of dinners for every day of the week because I’m sick of thinking of what to have for dinner every day. I’m very new to javascript so there might be several bugs and issues that I’m not aware of. Apologies for that and also for not using module config and defaults in the code.

Couple of things that could be improved with the help of your guidance

Stop function from being run every time MM is restarted or refreshed. Want to keep the list of dinners for a week.
Have the function run once a week at a set time. For instance Sunday at 6 pm (or maybe by button push)
Saturday and Sunday dinners should be from a different pick than the rest of the week. Want to eat less healthy on weekends
Have line breaks between elements of an array without using “textarea” and .join("\n")

Anyway, the code is pasted below. Hope you find it useful!

Why not upload it to GitHub or GitLab and then present it in the module showcase section?
