Prisma

I’ve worked though the entire *React + Apollo Tutorial*. I’m having a few issues around subscriptions. I notice on the page *Realtime Updates with GraphQL Subscriptions* in the second code block there is a variable `link`  that is defined but never used? Did I miss something earlier or is something missing here?

Ooh I think I figure it out.:

const client = new ApolloClient({
  link, // ** needs update here **
  cache: new InMemoryCache()
});

It doesn’t need an update, JavaScript supports passing the value directly if the key and value are the same.
