I'm surprised by the dearth of holistic frontend(web, app, desktop) literature. I'm looking for literature that goes under the hood of the frontend landscape and delivers fundamental and up to date insights around frontend technologies by "real experts".
I am putting forward the Increment frontend issue(https://increment.com/frontend/) as the best I've found.
I've checked Smashing Magazine but I never get a holistic feel from disparate articles by different people(https://www.smashingmagazine.com/category/react/)
I'm requesting content by top frontend experts that is holistic i.e. covers a significant section of a frontend framework, underlying technology etc. and delivers insight. This may be book(s), series of blog posts, magazines etc.
