I am maintaining an existing project, and I saw this:
The site is already including jQuery the traditional way (it's WordPress, and WordPress includes jQuery by default unless you change stuff).
<script src="cdn-or-local/jquery.js"></script>
And then the site is including another javascript file, which has been compiled with Webpack and Babel.
<script src="wordpress-theme/dist/whatever.js"></script>
On the original whatever.js file (not the compiled one, but the human-created one), it states:
import $ from 'jquery';
$(document).ready(() => {
...
}
And this confused me a lot.
As far as I know, if jQuery is already being loaded before the whatever.js file is loaded, then $ will already be defined.
Question: can I just safely omit import $ from 'jquery';?
