How to check if a user is already following a feed?

In order to check if a user already follows a feed , perhaps to render a different button or to avoid additional API calls, you can use the feed.Following() endpoint, for example, to check if user1 follows "scott" and "dani" user feeds,

const response = await user1.following({ 
  offset: 0, limit: 2, filter: ['user:scott', 'user:dani'] 
})
