title: How to make const for whole file?
body: <p>is there some way to make const for whole file? For example, get categoryId const, so that it can be used for <code>message.channel.send(categoryId)</code></p>
  <pre><code>module.exports = {
      name: 'new',
      description: &quot;Vytvoří novou sekci pro zákazníka&quot;,
      async execute(message, args, Discord, client, chalk){
          message.guild.channels.create(` | ${args[0]}`, { type: 'category' })
          .then(category =&gt; {const categoryId = (category.id)})
      
          message.channel.send(categoryId)
      }
  }
  </code></pre>
