Client-side web scripting is a huge niche, hence javascript is in the top spot. General purpose desktop/server applications are another huge niche, served by Java, C#, C++, C, Scala, Go (in that order). And so on.
It seems pretty sane, and the results have been stable enough to interpret the rise of upcoming languages and see the resilience of top contenders.

How to measure number of pageviews instead? I have a solution!

What I think many fans of any sort of language popularity survey miss is that there are huge swathes of the industry that simply don’t actively participate in things like SO and GH. All of these results should be qualified as “amongst webdevs” (sorry “full stack engineers”).
Even so, this article is also pretty bad. Nowhere does the author define what he means by "popularity", which is one of the key problems all of these popularity contests suffer.
If we say "Language X is more popular than language Y?" What does that mean? Answers could be any of:
* Total extant corpus of X is larger than Y.
* Number of people who know X is larger than Y.
* Amount of open source code in X is greater than Y.
* Number of people currently writing X (how much?) is greater than Y.
* Number of people who want to be writing X is greater than Y.
* Number of jobs available for writing X is greater than Y.
* Number of people talking about X is greater than Y.
These are all wildly different metrics but all have reasonable claims to represent "popularity" and/or are what some of these rankings claim to show.
To do anything useful, you really need to know what problem the reader is trying to solve and pick a metric that helps that problem. Is the reader trying to decide what language to learn to find a job today? To get ahead of the curve and be an expert in five years? To discover a new exciting language? To choose a language to use for a large, conservative project? A small ambitious one?
If I'm writing a game I care about what's most popular with games. If I'm writing an enterprise reservation system, I care about that.
These languages really live in completely different universes and I think it's time we acknowledge that. The one-size-fits-all survey of this sort feels like a holdover of a time when software development was far more homogeneous.
It's yet another example of how the entire profession is getting more specialized. You used to be a "programmer". Now you're a data engineer, ops engineer, front-end engineer, back-end/full-stack engineer, ios/android/react, system/OS programmer, etc. These are becoming entirely different jobs with little crossover between them, just like family law vs. criminal law vs. estate law vs. corporate law.

I still wonder when there's actually going to be official training in these specialties, that counts as credentials when seeking employment. As far as I know (and I could be wrong), traditional education tends to be somewhat general.
Which specialty you're qualified for seems to have more to do with what job you happened to hold when the specialization split began, rather than something you deliberately decided to study.
(Okay, I'll admit that there are training courses in all manner of things, but they don't seem like a formal course of study you can actually put on a resume.)
Actually a better question might be "What proportion of good programmers I interview will know a language in five years".
I ended up finding C#/.NET was listed on 33/50 recent job listings, Java was on 30/50 (some jobs had multiple languages listed), and other languages cropped up between 1-20 times or so.
So in my market, if I want a job where I don’t relocate (with a 3 year old and a baby and a wife who chooses not to work non-remote SV jobs are out), I’d better get to learning C#.
The question you need to ask is what decision is going to be impacted as the result of knowing the "popularity" of some language. The answer to that question will guide you towards the right metric you should be looking at.
Awhile back, I took a statistics class that explained how polling everyone by calling everyone with a phone landline resulted in a misrepresented sample.
The reason: not everyone has a phone landline. And those with phone landlines had a tendency to belong to specific demographics.
So...if you survey everyone using Github, and not every developer uses Github, are you not prone to the same fallacy?
I'm not sure if Cobol programmers use StackExchange (I guess they do).
Another relevant measure would be ALL jobs, not just available. Some people may not care if a million people are using language X if they're not getting paid for it.
But the sheer numbers cannot be ignored: Java / c# >> php >> Python >> Ruby/Rails >>>> Clojure... (Just one example)
Now you'd have to go into the details again to answer the question if you'd want to work at the problem set that is described in the job offer (how sophisticated, what kind of domain, how challenging,...)
Popularity by who searches for language help like Java or C/C++ is mostly because those are more difficult languages with bigger, historical sprawl and frameworks.
Just using searching for popularity is skewed because people search more so for things they don't know, than ones they do, and harder languages will probably be more searched. Same with tutorials, it only shows what people are learning. However it is somewhat valid in that even languages you use daily you end up searching for solutions and information on docs, community, etc.
The github and repo stats probably give a bigger picture of popularity combined with searching and surveys.
Side note: Personally I think everyone should learn C/C++ and maybe a functional language or a dynamic language like Python in addition to their main languages. Learning C/C++ and building in it is closer to the metal, has memory management and every language you learn after is less difficult. I do love C++ for game development but it helps with learning all other languages as well as all other languages difficulty is downhill from it, and is especially great for memory management, stack/heap understanding, value/reference understanding and C/C++ is empowering in the power/speed of the platforms. To this day still most apps are built with C/C++ under the hood whether directly, exported to or in a virtual machine that is built in it. For highly performant apps/code/systems C/C++ still are king.
Maybe object Pascal or rust for the less masochistic?
I’m ok with C if need be.
So, for me, searching is mainly related to the learning about a language, not so much using a language. This makes me wonder if the integral over time of search volumes might be a useful measure of language use?
Search engine result as well I'd be suspicious of. If I am searching a programming language it is something I don't use very often thus why I am looking up the information. The languages I use the most often I have stack of books on my desk rarely need to look anything up with a search engine.
Job prospects/salary is another ranking I'm interested in. For example, I know I can get a JavaScript job on any corner, but is that ubiquity going to cost me in salary? Can I earn more by mastering something like Rust, Elixir, or Erlang?
One of the takeaways is that there are different metrics and none of them is perfect.
So I grabbed what I could, combined them, and even had a JS thing where you could weight them differently.
Stuff I looked at: raw search, source code, books, job advertisements.
I would tend to focus more on job ads personally because those are at least linked to "real intent" to use a language for something tangible. You don't put it in an ad because something is controversial or had a lot of news lately etc. which can all lead to things being Googled a lot or getting a spurt of search activity.
Github's index is nice in that it is based on actual code, but then it's also heavily biased by what is open source and therefore doesn't fully reflect industry use of languages (which is why I think it deviates from other indexes to put Javascript and Python a bit higher, and less emphasis on say Java and C#).
Problems like this are part of why we have sayings like:
Measure twice, cut once.
GIGO (Garbage in, garbage out)
Some saying about measuring to extreme precision, then "cutting with an axe."
I always thought that had to do with carpentry and woodworking, not statistics.
Another interesting metric would be the number of open source libraries for the language that have had commits within the last 3 months and whose major semantic version is 1.0 or higher (or some other way to weed out unfinished libraries), sortable by license.
in the frontend world, it really is only Javascript, so I don't think we need a popularity contest there. and it's in use by practically all the websites in the world as a dynamic renderer.
but when comparing a language like Java, PHP, Node, Python, I really don't want to see the results of frontend Javascript skewing the results. otherwise, one would just assume Javascript is the most popular backend language, but that is not the case, as stated in the article.
article states that one of the rankings had Java as #1 and Javascript as #8. but on the other, JS was overwhelmingly #1 (because it combined both frontend and backend).
you need distinction because frontend and backend are like apples and oranges.
Measuring total corpus would be measuring past popularity and may miss trends. Search metrics on the other hand may actually overrate newer languages which may be searched more compared to more mature languages. Opened pull requests sounds like a better metric overall.
So it's really just a question of methodology. When TIOBE says popularity they must not be talking about usage rates, or if they are perhaps they are specifically sampling some subset of enterprise?
You should have doubts because every website you look at is on a device that most likely has tons of parts written in C.
Pretty much any piece of hardware you run your browser on, irrespective of whether you're looking at a website that has javascript code or not, has some C code running to support your javascript VM, browser, and operating system.
Whether you're on a computer, cell phone, gaming console, IoT device, you name it... you're most likely executing some C code quite frequently. And that's whether you're using a browser or not.
C is still the go-to language (no pun intended) for pretty much all drivers (with certain parts in assembly as needed) of any piece of hardware.
E.g., how many people are writing C, vs how many people are using things written in C.
If you count by total lines of code running in production, then the most likely winner is probably C or COBOL (decent chance your paycheck relies on large COBOL applications working correctly). If you count it by lines of code times number of running instances, then I'm really hard-pressed to pick any other language of C because of its sheer prevalence in things such as cars. If you count by number of programmers, I'm not sure what the winner ends up being.
Even crufty old languages like FORTRAN or COBOL have surprisingly wide usage. Sure, they may be completely absent in user-facing applications, but it's easy to forget that such applications are only a small portion of applications. JS itself would probably end up somewhere in the bottom half of the top 10 in most metrics of "top languages," as it has very little presence outside of user-facing applications.
By lines of production, it's definitely Javascript. COBOL doesn't come close. What was a lot of developer time in the 80s is dwarfed by the number of people around the world working on websites alone (much less this Node.js silliness).
More Javascript is written every day than is produced in C, all year due to lower barriers to entry, lower cost to fail, easier to debug, less (possible) side effects, and number of developers.
> it has very little presence outside of user-facing applications.
That's where most code ends up getting written. SMH
Just about everything around you that uses electricity is programmed with something other than JavaScript, including everything that runs JavaScript.
Take any big company, go to their jobs site and browse through tech jobs to get a rough sense of what portion involve building websites with Javascript.
As one random example, I just glanced at Bank of America (http://careers.bankofamerica.com/search-jobs.aspx), a $300bn company that employees 200k people, and if I look at "Technology", I see pages of Java/ .Net/ Hadoop roles before I get to the first UI/ website/ frontend one.
It'd be interesting, and no more or less valid, to see how many paper books and ebooks have been sold on each.
GitHub takes count of the projects on its own site in each language, but that microcosm may not represent other places. Anecdotally, my employer runs private git repos on private servers, and our ratios don't match GitHub's.
Another interesting metric would be number of job openings. Another would be average pay for a developer mainly using a particular language. Another would be asking people in a scientific poll which languages they use and which ones they enjoy using.
