Hi Tari.
I struggled to learn web dev for a couple years as well. It's a lot to learn, and the fact that you've kept at it this long is worth being proud of!
For resources, I recommend Kent C Dodds. He has done a lot in and for the React community, including creating a ton of blog posts, courses, and workshops, all around React, and Javascript. He even has a post specifically about what Javascript features you should know before learning React. I'd start there!
I am also willing to help answer any questions. You can find me here which has a link to my twitter. DMs always open.
Keep that momentum up!
