title: JavaScript - use apostrophes or quotation marks?
body: <p>For string literals, are any differences between using apostrophes or using quotes? I'm thinking in regard to performance, functionality, conventions, etc.</p>
  
  <p>To clarify:</p>
  
  <pre><code>'Hello!'
  </code></pre>
  
  <p>vs.</p>
  
  <pre><code>"Hello!"
  </code></pre>
  
  <p>(for want of a more imaginative string)</p>
