It's always been a little overwhelming but in the past few years it's definitely increased. I stick to learning only what is sensibly required for the project, which can be complicated enough if that means React, redux, GraphQL, Angular, NgRx, etc. The time to learn comes when there is an actual need to build something on a reliable, widely adopted tool/framework. You learned this much and you won't forget how to learn. Trying to learn everything on the rapidly expanding edge is not necessary. If you still feel compelled to learn something on the frontier pick a small area to make it scale. Otherwise yeah Javascript has become only more insanely complicated lately.
