Fullstack developer?

and can someone please help me, that which all sections need to be completed for full stack developer on free code camp??
and also which technologies are required for mean stack need to be completed on free code camp???

Well, since the curriculum is a full stack, all of them. FCC teaches MERN stack, so if you want to do MEAN stack, you’ll need to do Angular instead of React.

The technologies for MEAN stack are detailed at mean.io.
