I read the comments of people that after all a programmer is not the best profession in terms of salary. I want to know what a good web programmer needs to know, and not just a simple php coder. Does a web programmer need to learn how to work with languages like C ++ / C / pascal? What role do java and C # play in web programming?
Then, after everything below it is written, where you can clarify what is required to know the web programmer. Everywhere they write php, mysql, html, javascript, css, is it enough or what else should a good programmer know and be able to do?
Then, after everything described below, I had another question. Is there any point for a web programmer to know one of the languages such as C ++, Java, C #?
