Really? Functional reactive programming, immutable data, unidirectional data flow, application state as a fold over a stream of actions... it seems like web development is seeing a really high uptake of valuable, transferable abstractions and ideas, far more than mobile GUI toolkits, for example.

JavaScript programming is, CSS and HTML not so much. I would also argue that the details of frameworks like Angular also fall in the "garbage knowledge" pile.

Fair enough, you meant to refer to a subset of web development, rather than the entire field. It's a significantly weaker claim, though. I could pick out subsets of any field of work, and declare them non-transferable, and the details of most systems are going to be less transferable than the concepts undergirding them.
