What is the meaning of front-end?

Question

JavaScript

Why build a website structure in js? Why are you not satisfied with the usual layout? SingPageApplication is like a one-page but multi-page site, what's the point? And where to start learning js (front end)? (I know jquery) Is it possible to write a front without Beck?

Answer 1

Why are you not satisfied with the usual layout?

meaning in:
- one API for different clients - Android, iPhone and web, if it weren't there - then API for mobile and separate controllers and actions for the web application would be done
- low dependence of the front-end developer on the back-end code, hence the high concentration on js and frontend - higher expertise, also the front can be changed as much as you like - the backend is iron and vice versa
- faster - a lot of html is not loaded from the server, only one json goes and the load on the server is lower
- fashion

Frontend in JS allows you to completely separate the frontend application from the backend application (in different projects).
And after that, I, a backend developer, don’t have to think about the front-end and deal with it.
This is a clearer organization of logic, which translates into more efficient and cheaper development of the application, significantly reduces the cost of support.
Yes, after such a separation.
