I want to make and understand complex JS libraries like swiper or @apollo-client. It is quite obscure to search online and it goes without saying that my college classes did not include it.
I am willing to take the time and effort to learn and understand it.
I suppose I could peer into a node_modules folder and analyze, but surely there must have been a class or set of documents online that teach about this.
Where may I find the place where I can learn about building and understanding a complex JS library?
