You should google more.
I see this common in software development where when people are looking for a simple thing, they google often.
“promise in javascript” “HTML video tag”
But when they are having trouble with some advanced topic, they don’t google it.
They either somehow do it haphazardly or just get purely stuck.
People have written articles and given talks on advanced topics too.
So if you just google it and learn from that resource, you will know better than what you know now.
Keep going through many such resources and you will finally understand that advanced topic well enough to properly implement it.
