- Process incoming client requests and connect to external databases using standard REST HTTP methods (GET, POST, PUT, DELETE).
Pre Requisites
- A firm grasp of JavaScript basics. You should be comfortable with variables, functions, and standard web concepts before tackling back-end logic.
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
