body: <pre><code>$("#ID").hide();
  </code></pre>
  
  <p>i add ESLint to  my project .</p>
  
  <p>everything is fine, except symbol <code>$</code>.</p>
  
  <p>i get error: <code>[eslint] '$' is not defined. (no-undef)</code></p>
  
  <p>my <code>.eslintrc.json</code> (note: it has <a href="https://github.com/dgraham/eslint-plugin-jquery" rel="noreferrer">additional rules</a> set to disallow jquery functions when there's an equivalent javascript one):</p>

  <p>you can see that I have added two plugins: <a href="https://www.npmjs.com/package/eslint-plugin-dollar-sign" rel="noreferrer">eslint-plugin-dollar-sign</a> and eslint-plugin-jquery.</p>
  
  <p>why does not work this rule ?</p>
