Feedback

ENS

1. The copy button in the ENS docs on docs pages (like this one) doesn't work, the copied text is "undefined".
2. The code snippet on this page relies on a "ens-core" import that I couldn't find/install.
3. On that same previous page, if you reuse the code snippet, you will get the following error:

Type 'GetEnsNameReturnType | undefined' is not assignable to type 'string | undefined'.
  Type 'null' is not assignable to type 'string | undefined'
