You don't use a programming language to get a job, you use it to give instructions to a computer. You asking that question already says it all, you aren't going anywhere in this industry. The fact that people even do things like leetcode is laughable to me. If you haven't already found a single thing that inspired you to program just for the fact that you want to make something, which I know you haven't or you would have already shed the concept of caring about what the most common or best language is, what makes you think you can do it as a career competing against millions of people that were already living and breathing programming for free because they love doing it?
