Personally, I do find back-end easier to reason about than FE, although it will almost certainly depend on your choice of language/framework to a greater or lesser extent. In C# MVC (Or PHP MVC like Yii which is very similar), you have a very clear separation of what is what. A single action is where most functionality will sit or be called from. A view is where most front-end code sits (and if writing APIs, this is largely not relevant). Models are for the most part just data properties, perhaps with atributes for validation. Debugging it for the complicated cases is still very easy. My experience in front-end is that debugging is very difficult. It is not easy to follow the path of execution, partly because of the large complexity of libraries/web-packing type stuff and partly probably depends on the tools you use. You have to consider a LOT of state in anything other than easy applications. I guess these might get better over time as people learn what works and what really doesn't but most of the larger FE frameworks have all had large changes to their patterns/opinions in a relatively short space of time. I also don't why but I find C# much easier to read and understand than JS even though JS is based on the same syntax style. Again, might be the tooling, coding style or just the complexity of things like Vue classes but I can't easily review JS (or TS) code whereas I can spot mistakes in C# from miles away. Like other have said though ymmv and whatever you do, you always need to keep up, keep learning and believe in yourself.
