PageSpeed Mobile - Third Party Code and Minimize main-thread work

[lillycue]

Hello Lovelies :3 I've been working on my website, Cute Darkness,  browsing experience and the PageSpeed score. I managed to improve it a lot by optimizing my images, using js and css minification, and lazyload, amongst other things. I got results so far, but there's a big culprit in all this, Shopify itself.  

As you can see jquery and min.js are the biggest offenders in third party codes section. As well as Script and Evaluation and Style & Layout in Minimize main-thread work section. I use a couple of apps to add features to my store, but I'm slowly learning how to code to run some of these features natively. I don't know what exactly I need to do, I installed the latest jQuery version in my store, but I don't know how to proceed with this or even if it was a good idea in the first place. Does anyone know how to reduce these values? Thank you

Hi there,
Your speed is slow becasue of those reasons
- Google Page Speed shows the codes /s/trekkie.storefront.., which means that the theme you are using is heavy
- You can change to other theme such as Dawn theme ( free)
