I never liked NodeJS; on the one side it was innovative in that its concurrency model allowed for faster back-ends, but a lot of the features of existing back-end languages like Java and PHP were still missing, so a lot of patterns were re-invented, the language itself needed years to get to the 'safety' levels that Java already had and PHP was working towards, and proven and standardized technology like XML and the contractual guarantees it could give were discarded because it was heavy and JSON was better because it was human-read/writeable or something like that.

I feel like we lost a lot of time and effort by ditching XML. I mean documenting a REST/JSON API is still painful. While 20, 25 years ago you could already generate your data models and a parser for your XML payload. I still don't know what was wrong with XML. Yeah it was a bit heavier on the line than JSON, but that's a fixable problem - using compression, or use EXI (https://www.w3.org/TR/exi/) to turn it into a binary protocol. I don't know if EXI ever became a thing, but at the time I was quite exited about it knowing how much XML was passed around.
