Where should jQuery code go in header or footer?

jQueryWeb DevelopmentFront End Technology

It’s always a good practice to add jQuery code in footer i.e. just before the closing </body> tag. If you have not done that, then use the defer attribute.

Use defer attribute so the web browser knows to download your scripts after the HTML downloaded −

<script src="new.js" defer="defer"></script>

The defer attribute is used to specify that the script execution occurs when the page loads. It is useful only for external scripts and is a boolean attribute.


The following code shows how to use the defer attribute −

<!DOCTYPE html>
      <script src="new.js" defer></script>
      <p>The external file added will load later, since we're using defer</p>
