Nowadays, many people strive to conquer the heights of programming in one language or another. There are debates about which language is better, which is more productive, many developers and beginners focus on benchmarks and foam at the mouth to prove something to each other. This is so childish and so pointless!
Ask yourself the question, what will you create using this or that language? Do you have a startup idea? Can you create something new? Remake an existing one, but make it 10 times better?
If you are offered a job or take tests and interviews, you will be given technologies that you will be required to use. Business, money, and interests of managers who have never written code themselves will carry more weight than the results of your research and study of effective programming languages. This is the fucking reality of the industry today!
Therefore, you need to learn something else: physics, mathematics, chemistry, neurobiology, any natural science. This will give you the opportunity to write something in your favorite programming languages that someone else really needs. Not boring schedules and product lists, mailings and stores, fuck commerce.
Natural on, that's what should advance your programming knowledge!
I work in a company with other people. it's not a good idea to have an idea where you have to specialise in a range of things to be successful. I specialise in programming.
also, those benchmarks translate to better user experience which means they actually use our product, and lower hosting costs.
frameworks and patterns reduce bugs and let us create features quickly. it's important, if you think it's pointless maybe it's not for you. if you want to go do a startup instead, good luck.
