title: What is the . specifier in Kotlin
body: <pre><code>private object Bot {
      val jda: JDA = JDABuilder.createDefault(&quot;token&quot;)
          .setActivity(Activity.watching(&quot;something&quot;))
          .build()
  </code></pre>
  <p>}</p>
  <p>I see a lot of these thing where you specify the parameters using . and indents. What's it called and how does it work?</p>
