Do front-end developers need to learn back-end?

Question

Python

I write in javascript, I know well all the top frameworks, tools, nodejs ... but as a rule, wherever I manage to work, the backend is written in php. I have experience with php, but rather meager. Will learning php, its frameworks, CMS give me additional benefits, or is it better to further hone javascript, frontend, raise my English level ...?

Answer 2

Improve front-end and knowledge of English.
Frontenders work for us, they don’t know PHP at all, but they know the principles of backend implementation (because they work on JS).
They write smart applications for our APIs.
The comrades are fully concentrated on the front and this is what gives them an advantage.
It is quite difficult to find a strong specialist in your field. It is not worth sitting on 2 chairs in our time.

Answer 3

It is important to know and understand the interaction with the backend API. The language can be any, but you will not learn every one of them.

Answer 4

IMHO you should not be scattered, upgrade your knowledge in the frontend, especially if everything changes almost every week

Answer 5

In short: No.
It is worth focusing on the front-end and how the front-end interacts with the back-end (http requests, headers, etc.).
It might be nice to understand the basic syntax of the language, but that's just a bonus.
