title: Odoo Loading Javascript
body: <p>I don't really understand how to load Javascript in Odoo. On Odoo official website, it mentions:</p>
  <p>web.assets_backend: this bundle contains the code specific to the web client (notably the web client/action manager/views)</p>
  <p>web.assets_frontend: this bundle is about all that is specific to the public website: ecommerce, portal, forum, blog, …</p>
  <p>The part I don't understand is what defines a thing is 'web client' or 'public website'. Is there a sign to identify this?</p>
  <p>The way I loaded my JS file until now is to try 1 way or another, either 'assets_backend' or 'assets_frontend'.</p>
