My fav Udemy course is a bash shell scripting course[0] . The content is worth reviewing especially for any beginner/intermediate sysadmins/devops/backend devs.

Another one I like is an intermediate js one JavaScript: Understanding the Weird Parts[1]

+1 for Understanding the Weird Parts

It's a good course that explains things from first principles.
