Becoming a full-stack developer typically takes 3 months to 1 year, depending on the amount of time you can dedicate to learning. For example, if you can dedicate 30-40 hours a week it can take 3-4 months to become a full stack developer, whereas if you can spend 10-15 hours a week it could take up to one year.

Web developers specialize in either front-end (user interface) or back-end (server-side) development, while full-stack developers work on both. Full-stack developers handle the entire web application, from design to database management. So, a full-stack developer is a type of web developer, but not all web developers are full-stack.

Yes, you can become a full-stack developer without experience. Employers often prioritize job applicants who can demonstrate the skills needed to be successful. Online classes - like those offered by Udemy - can provide the skills and projects that can route you to a full-stack developer career.
