My 2 cents. I would consider myself a JS expert as I have writen AngularJS and RequireJS clones. Personally, I don't agree with the path that OS JS dev has gone in recent years. The reliance on build systems and transpilers are fundamentally anathema to the spirit of simplicity and low barrier to entry that attracted me to the language and ecosystem inn the first place.
I understand that as we have moved from web pages to web apps the increase in complexity was inevitable, but I question a lot of the tools being used now. For one thing, once we moved to creating full applications using JS, one of the concerns that tooling moved to address was maintainability. This is why MV* caught on and destroyed JQuery as a viable option for many projects. That being said, Angular pretty quickly swapped one kind of maintainability problem (refactorability) for another (over-abstraction and cyclomatic complexity).
As for the dev tooling (webpack and company), one of the reason I avoid a lot of them is in my experience they can get in the way of maintainability. For example, I recently tried to pick up a 3 month old project in Android Studio and it took me around 3 hours just to get it to compile again because of updates and other tooling complexity. This NEVER happened using Eclipse. The same thing is happening and will happen when the apps being built today get dumped on some poor sod 3-5 years from now.
Lastly, an example from my job. I was recently asked to update the verbiage on a sign in form built ~13 years ago. The devs decided to use some java framework that had buzz at the time named JATO. Jato literally doesn't exist anymore and building it is basically impossible. This is to say nothing of modifying it as all documentation has literally disappeared from the web. The devs picked JATO b/c they thought it would be easier to modify and maintain. Exactly the opposite has happened. They could easily have written the form (literally two input boxes and a submit) using plain JSP. If they had, that code would still be useful today.
