I' am using quick.db to store objects in the database using
db.set('object', 'A random text')
So how would I store an argument
db.set('argument', args.slice(1).join(" ")) // This won't work I guess
After storing an argument into the database I want to push it to the channel.
I can't say for sure because you provided so little information, but I'm guessing your issue is that the args is meant to be a dictionary, and you are currently joining it to a string.
// Setting an object in the database:
db.set('userInfo', { difficulty: 'Easy' })
// -> { difficulty: 'Easy' }
Hopefully this helps.
