I had posted this a while back but got no answers so here I am reposting!

I know what a weak table is, just looking for use cases for them.
Question
From my understanding, you can set the values of a table to be weak with like this:
local x, m = {}, {__mode = 'v'}
setmetatable(x, m)
You can also set the keys to be weak with __mode = 'k' and both the keys and values with __mode = "kv".
So my question is this:
What are weak tables useful for? Will I find myself using them in the future?

Side note: Do not answer this question unless you 100% know what you're doing. We don't want a repeat of random people dishing out stupid answers.
I don't have time to write a full answer today, but I can answer the final question: "Will I find myself using them in the future?" > No, you very probably won't.
