Combining External Javascript

Can anybody help with this situation, where site speed tests are telling me i need to combing external javascript in order to speed up my site. I have no clue as how to do this.

thanks

What external Javascript are you referring to? Wix handles optimization of code libraries and page rendering. Speed sites use methods that do not necessarily have a full understanding of all of the complex decisions and actions applied by Wix to code and page handling.

If you need further details or clarification, I would recommend contacting the Wix support team , as they can provide more information concerning this subject.
