JavaScript (JS) files - Site Speed

[LAGE24]

The JavaScript (JS) files in my store are contributing to an increased Total Blocking Time (TBT) score.

I need to speed up my site especially mobile as its terribly low.

I'm guessing it's something I can't do myself?

Any tips on anyone to help on this one. UK based preferably.

Hi Lage, 

Depends on what the JS is doing as to if you need a Developer. 

Likely you are using external libraries in your theme which will need to be removed and then see if we can use CSS or plain JS to perform the same functionality. 

We are U.K based (Shropshire & London developers) so feel free to reach out: support@flairconsultancy.com 

Kind regards, Liam
