Here comes the question. Is there a way to override some of the js code, by making another "version" of them in the footer? I actually plan to make footer load a js file instead, including overrides, but since I barely know how it will behave, I thought I should ask if I think this right.
It might add to the amount of download plaintext that way. It isn't elegant, since it turns things a little spaghetti, but I plan in the future to make any js call, a call to a js file thus no footer override will be needed and no double code will be downloaded whatsoever, I just need a fast solution for the meantime. I asssume if I add to the amount of download plaintext, I will still might get parallel loading of scripts in compensation, thus loading time will get improved.
Pictures are small jpgs and they don't contribute on loading time in a significant way.
PageSpeed Score is 74% so there is a lot room for improvement. CSS and JS are the major factors.
Do I think this right? Any guides will be appreciated.
