Is it necessary to know BEM front-end for a coder?

Question

BEM

Good afternoon, after reading a bunch of information and listening to all the pros and cons of BEM, I would like to know if it is worth learning BEM for a beginner coder, or are there alternatives now, or is it better not to use it at all?
Or is it generally better to use preprocessors like less?

Answer 1

No. And judging by the question, you do not understand what it is. My personal opinion: it is better not to use.
