title: Array map equivalent for GraphQL query
body: <p>I was wondering if it is possible to reduce the return payload of this query Result:</p>
  
  <pre class="lang-json prettyprint-override"><code>{
    "nodes": [
      {
        "topic": {
          "name": "typescript"
        }
      },
      {
        "topic": {
          "name": "discord"
        }
      },
      {
        "topic": {
          "name": "discord-bot"
        }
      },
      {
        "topic": {
          "name": "discordjs"
        }
      },
      {
        "topic": {
          "name": "discordjs-commando"
        }
      },
      {
        "topic": {
          "name": "mbti-personality"
        }
      },
      {
        "topic": {
          "name": "mbti"
        }
      },
      {
        "topic": {
          "name": "typeorm"
        }
      }
    ]
  }
  </code></pre>
  
  <p>Into something like this:</p>
  
  <pre class="lang-json prettyprint-override"><code>{
    "nodes": ["typescript", "discord", "discord-bot", "discordjs", "discordjs-commando", "mbti-personality", "mbti", "typeorm"]
  }
  </code></pre>
  
  <p>I find it very verbose and unnecessary</p>
  
  <p>I am not the owner of the API. So that concerns only the <strong>query</strong>. (It the Github's GraphQL API)</p>
  
  <p>I'm new to GraphQL and don't undestand the principles yet, so I don't know the terms to search for.</p>
