Older developers in the Node ecosystem still sometimes write callback hells, but it's true that it's less prevalent than in the .NET world.

The problem is that I am the one who has to maintain that code. The reality is that code ultimately follows the prevailing trends and paradigms of its era. Most developers tend to stop growing around their 5th to 7th year (this is purely my observation). They settle into the complacency of having shipped a single complete program, an experience they usually hit around their 4th year. As a result, when you do actual maintenance work, you end up facing things like C++98 code or .NET codebases where the dependency graph is a complete disaster.

Compounding the issue is that these types of companies have very little technical exchange with the outside world. And that specific way of writing code ends up acting as a sort of gatekeeping mechanism.

Sometimes, I feel like programming ultimately boils down to how well you can read and adapt to these shifts in paradigms. The coding trends of today will likely become the outdated legacy of tomorrow, and someone might eventually tell me, "You write old code." It is always a difficult problem.
