title: How can I check if the message author has an admin role using Discord.js?
body: <p>I'm building a Discord bot and I want to have an <code>if</code> statement that will only proceed if the message author has an administrator role in the guild.</p>
  
  <p>I've tried having role-specific permissions, but this means that there will have to be the exact same name role on all servers that the bot is on.</p>
  
  <p>How can I check if the message author has an admin role? (The role has the administrator permission.)</p>
