What to prepare for when moving from back end to front end?

Question

Career in IT

Hello!
After two years of development in java, I would like to try my hand at the front-end, because sometimes the complete absence of a result visible to the user in the case of the backend does not please.
How long will it take to learn at the front enough to get a job (I understand that the salary will be lower)? Will knowledge from the back on the database, architecture, patterns come in handy?

Answer 1

Knowledge will come in handy, because. A normal front-end developer should know how the back-end works and how to properly interact with it.
As for skills, keep a good picchu, it's relevant enough.

Answer 2

(I understand that the salary will be lower)?

But why?
But why?
I was frontend at the beginning, moved to backend and don't want to go back. If you are not invited to develop constructors, frameworks, games, complex animations, then only forms, forms, beautiful buttons, form layout, okay, I exaggerate, a slider can still be waiting for you ... but although not, it already exists in another lib.
No and yes. The database will not come in handy, because you don’t work with it, the architecture will come in handy, ... no, one will have to deal with the architecture of the application being developed. A lot depends on how they develop in the office. In one I remember writing JS through the module pattern, because all scripts in one file
Description of the pattern, good enough , in another office on the first day they told me "Wow, wow, palehche guy, we have scripts in different files, so forget it."
If you understand front-end layout, then definitely hammer it in, the routine is still the same. Better rivet the layout designer.
You already have an idea, so a month is the maximum. In the world of layout, you can lay out EVERYTHING with one div tag, with forms more complicated, there are three tags form, input, submit. In short, 4 tags, well, also body, head and title. All other tags are "semantic" and seo-shit is a profanity for true proger in the form of blanks with built-in css. In short, thanks to me, you have already learned the main 7 tags in html. You can already start taking orders for 2 bucks an hour, you will be cooler than any Indian.
Damn, I got carried away, but the truth is out there somewhere. :D

Answer 3

Read the text backwards and tell you to answer the following:
'After two years of development on the front end, I would like to try my hand at the back end, because the ability to create empty interfaces without a real application is not encouraging.
How long does it take to learn backend java enough to get a job?
Will front-end knowledge of algorithms, OOP, patterns and architecture be useful in the back-end?"

Answer 4

Will come in handy, the name of this is a full stack
If there is no understanding of the basics - html / css - teach)
depends only on you. You can grow up to a confident layout designer in a month, but the farther into the forest, the more JS.
