What technologies do Full Stack web devs need to know?

Question

IT education

Hello. A question? What technologies do you need to know for a programmer positioning himself as a Web Full Stack developer? For example, I'm learning Node.js part of the backend. What else do you need to know? It seems that those people who are engaged in HTML and CSS are called layout designers, but from the front-end side, you only need JS and some kind of framework? Or would learning HTML/CSS be a plus too?

Answer 1

HTML / CSS is the basis without which you, as a "backend" developer, will not go far.
But in fact, the answer is in your own question: a programmer positioning himself as a Web Full Stack developer needs to know the "Full stack" of technologies.
Starting from the concept of a server (apache, nginx), how HTTPS works, ending with advanced layout (how a browser works, how a page is rendered)
