Consume all knick knacks in your inventory - Really! Or maybe?

knick-knack-bot.js

/*
Removed useless info about the author - advertise yourself if you actually know what you're doing - THX!
Probably not one single bit is left from the original source, since Mister Advertiser actually ignored
all the different item-types. Kerikek (sleep is my copy-pasta of another copy-pasta ...∞)

So how to use this crap?
1. you don't need to load your inventory, but it would be a good idea to reload the site one time before you start
(your inventory site -> https://steamcommunity.com/my/inventory/)
2. open your developer-tools and go to console (maybe press F12)
3. paste this script to your console and execute it by hitting enter if you want to consume all your knick knacks
4. the script will log the progress to your console, no fancy dialog-box sorry ain't got no more 2 mins
5. the script will reload the site after it finished
6. you should leave the tab with the script running, open, or use a separate window to run it (NOT TAB!)

BONUS:
change   kk.consumeAmount();   to   await kk.checkAmount(); | to get the total of knick knacks you got in your inventory
change   kk.consumeAmount();   to   kk.consumeAmount(x);    | x = number of knick knacks you want to consume
change   kk.consumeAmount();   to   kk.consumeAmount(x,y);  | x = look above, y = delay between requests

Works much better than the original one. Thanks mate!
