Sometimes java is best in industry , sometimes python , sometimes c++ , or other . Why it is like this ? who is making best each other ? Actually it is existing or any marketing trick ?
There is no "best". They're just tools to accomplish tasks. If I write a web server in Assembly or I write it in Basic, the end user doesn't care at all. They only care that the server works. If you're looking for what to use, then I'd say just choose the most common thing, there will be more jobs and better documentation.
