title: how ignore typescript errors with @ts-ignore?
body: <p>I have a case where I'm importing a puraly JavaScript library within TypeScript project giving me the nagging <code>Could not find a declaration file for module xxx</code> message. So after reading I found I can supress that with a comment with <code>@ts-ignore</code>. Yet adding that comment before the offending line, I get another error</p>
  
  <blockquote>
    <p>Do not use "// @ts-ignore" comments because they suppress compilation errors  @typescript-eslint/ban-ts-ignore</p>
  </blockquote>
  
  <p>How can I fix this error and suppress the original message?</p>
