map() like function on Collections that uses function argument as key instead.

Hi,

Currently .filter() is a custom implementation that returns a filtered map with the ID being they key. .map() returns an array, consistent with Javascript documentation. Is it possible to implement a function that allows for the Collection to return a map that can return a map with a different key as for instance such as channel.name -> channel etc.

I wrote and got a reply in the wrong repo about this feature request here discordjs/discord.js#6645

I looked into it again, and if you don't want to transform the key there is https://discord.js.org/#/docs/collection/main/class/Collection?scrollTo=mapValues
