Using mem with many-keys-map

[papb]

Hello @fregante, I noticed that you are a maintainer of mem and also the owner of many-keys-map. Is there an easy way to create a memoized version of a function with multiple arguments by internally using your many-keys-map as a cache keeper? Thanks!

[fregante]

Yes, I think you need this:

mem(fn, {
  cache: new ManyKeysMap(),
  cacheKey: args => args
});

Thanks for the fast response, I will try it out later, and if I have trouble I will post here.

@fregante If it works, this would be a good tip for the readme.
