Do I need to know bootstrap & gitshub to become a web developer?

Question

I want to know about bootstrap & gitshub briefly.

Answer 1

These two aren't that important to develop a website, but you can learn how to use them to make it better...
The very important languages to know about web dev are:
;;;;HTML (main and design);;; CSS (styling and animation);; JS (scripting, events ...) ;(and maybe PHP)
