I think this really depends on what you want you're looking for. I agree with you in so far, that I don't think Udemy is particularly good for providing some solid theoretical (or semi-theoretical) basis for any given programming topic. I usually just use books (or sometimes coursera courses) for that. Udemy courses, however, are pretty good at providing you a decent idea of how to apply knowledge in a given domain to a specific problem without going into too much theoretical detail. To give an example, if you need to get up to speed with React in short time and you just want to see how one would structure or build one, two react projects, simply get a high-rated udemy course on react and you'll get a pretty decent idea. Sure, you could read the docs and then go through some popular github react projects and learn it that way. But I do enjoy just coding along every now and then, and I think it's fairly good at that.
