In Elixir there’s something called [ETS](https://elixir-lang.org/getting-started/mix-otp/ets.html) which is basically a caching system, I was wondering if there’s something like that in Julia?

I don’t know ETS, but if you are looking for [memoization](https://en.wikipedia.org/wiki/Memoization), there is

or you can easily implement something custom yourself.
