it was an acronym some anon came up with to go by when writing javascript (or judging others' use of javascript more likely lol), wasn't a big thread or anything, just a reply to someone else. I saved it but the external hard drive I had it on fucked up (don't buy toshiba HDDs, lads). I can't exactly remember what it stood for, but it was something like this
Minimal: your javascript should do its job with as little lines of code as possible, keep things simple, avoid bloat, overengineering, etc.
Optional: website should work just as well with JS disabled as it does with it enabled. There should be no compromise in usability if the user chooses not to load your javascript
Last-resort: only use javascript if there is no other way to do it; if the effect you want to achieve is impossible using just HTML/CSS (or server-side scripting I guess)
Useful: self-explanatory, your javascript code should do something useful
Safe/secure (I think): self-exp. again, but I'm not fully certain that I remember the word correctly
Kosher: can't for the life of me remember what this one stands for. something about standards compliance maybe?
I definitely misremembered a lot of that, but maybe there's a chance someone else remembers (or even the person who wrote it). otherwise post rules/guidelines you work by when writing JS, tips 'n' tricks to make it less of a pain to deal with, etc.
