The most popular programming languages are rapidly changing

Interesting post on Quartz:  The most popular programming languages are rapidly changing

While it is an interesting post, a number of questions came to mind on reading it:

  1. While StackOverflow is indeed a dominant system for developers seeking and sharing information, I wonder if its demographics is really representative of the entire software/technology industry.
  2. The dominance of JavaScript is hardly surprising, since if you want to do anything in the browser, you really have no choice (and choice is always a bad thing, right?).
  3. Is SQL a “programming language”? I never thought so. You cannot “build a system” in SQL – SQL may be a major part of a large number of systems, but you need a programming language to make use of it.
  4. NodeJS and AngularJS are not programming languages. They are frameworks for JavaScript. Making these two their own categories makes no sense, anymore than it would make sense to have separate categories for Python and Django and Tornado. It might make sense to have separate categories for server-side versus client-side Javascript, but not specific frameworks.
  5. Merging together the JavaScript, NodeJS and AngularJS would give a more clear indication of the use of Javascript – rather than showing a decline in JavaScript usage over the last three years.
