/core is a subpackage that doesn't have all the "hand holding" you get with discord.js. If you know what you're doing, or know why would you want to, you're probably good to go with /core, otherwise discord.js is most likely the one you should use.

That said, the old. subdomain is overall confusing. The reason that's done this way is because the new docs only work with TypeScript code, and discord.js itself is the only thing that is still in JavaScript. The reasoning shouldn't really be "old version of d.js" but "old version of docs", because there isn't a newer version of discord.js (guide has a v13 subdomain for "legacy" content if you need it, but the main address displays current content).

When The Eventual TypeScript Rewrite™️ of discord.js will happen, it will be on the new docs as discord.js just fine, alongside all the other subpackages.

We‘re always happy about feedback. What parts of the new docs do you deem worse than ever and how are the old docs better in that aspect?

Well, I'll ignore the fact I loved that old style.

Maybe for you the points I'm going to say are all refutable, but know that I'm just an average user with 2IQ

Besides the style, the search system doesn't seem to be straight, it feels like sometimes I'm typing an exact thing and that isn't the first item of the results
2. The navbar also seems to be with too much (I know it's supposed to have everything, but maybe there's a solution for this)

That's what I can notice, but it clearly feels slower than the old one
