I've recently started using Express.js for a project at work, and I've never before encountered a seemingly popular framework/language with such frustrating content churned out by the community. Express's official docs have all the technical specs you could ask for, but the framework is very light weight without any structure and feels more like a library, sort of like Flask. I wanted to see what a typical app structure looks like, but just about every single "article" I found was either a copy/paste of the same app with everything crammed into one index.js file (routing, logic, db queries, etc...), or they were walls of text filled with occasional code snippets and didn't even provide a repo for reference. The community feels like it's targeting complete beginners with its simple examples, lengthy explanations of trivial tasks and extremely little coverage of architecture. My experience with Express felt like PHP 10 years ago with w3schools.

Or SO answers from 2011, pasting official docs.
