In our aim of making an attempt to estimate a programming language’s reputation, we realized that nobody can look over the shoulder of each particular person writing code, whether or not that be a baby writing a Java script for a private Minecraft server, a cellular app developer hoping to hit it massive, or an aerospace engineer writing mission-critical code for a voyage to Mars. Our Top Programming Languages interactive tries to sort out the issue of estimating a language’s reputation.
We do that by establishing measures of recognition from a wide range of knowledge sources that we consider are good proxies for energetic curiosity for every programming language. In complete we establish 59 programming languages. We then weight every knowledge supply to create an total index of recognition. Below, we describe the sources of information we use to get the measures, and the weighting scheme we use to supply the general indices.
By reputation, we imply we try to rank languages which can be in energetic use. We take a look at three completely different elements of recognition: languages in energetic use amongst typical IEEE members and dealing software program engineers (the “Spectrum” rating), languages which can be in demand by employers (the “Jobs” rating), and languages which can be within the zeitgeist (the “Trending” rating).
We gauged the recognition of languages utilizing the next sources for a complete of eight metrics (see under). We gathered the data for all metrics in June–July 2023. The knowledge have been gathered manually to keep away from outcomes being biased as a result of API adjustments or terminations and since most of the programming language’s names (C++, Scheme) collided with frequent phrases present in analysis papers and job adverts or have been tough for a search engine to parse. When a lot of search outcomes made it impractical to resolve ambiguities by analyzing all of them individually, we used a pattern of every knowledge supply, and decided the related pattern measurement based mostly on estimating the true imply with 95 % confidence. Not all knowledge sources include info for every programming language and we interpret this info because the programming language having “no hits” (i.e., not being in style).
The outcomes from every metric are normalized to supply a relative reputation rating between 0 and 1. Then the person metrics are multiplied by a weight issue, mixed, and the outcome renormalized to supply an combination reputation rating.
In aggregating metrics, we hope to compensate for statistical quirks that may distort a language’s reputation rating in any specific supply of information. Varying the load components permits us to create the completely different outcomes for the Spectrum, Jobs, and Trending rankings. We totally acknowledge that, whereas these weights are subjective, they’re based mostly on our understanding of the sources and our prior protection of software program matters. Varying the load components permits us to emphasise various kinds of reputation and produce the completely different reputation rankings. We then mixed every weighted knowledge supply for every program after which renormalized the ensuing frequency to supply an combination reputation rating. In aggregating throughout every knowledge supply, we hope to compensate for statistical quirks that may distort a language’s reputation rating in any specific supply of information.
The Top Programming Languages was initially created by knowledge journalist Nick Diakopoulos. Our statistical methodology advisor is Hilary Wething. Rankings are computed utilizing R.
Google is the main search engine on the planet, making it a perfect match for estimating language reputation. We measured the variety of hits for every language by looking out on the template, “X programming language” (with citation marks) and manually recorded the variety of outcomes that have been returned by the search. We took the measurement in June 2023. We like this measure as a result of it signifies the quantity of on-line info sources about every programming language.
Stack Overflow
Stack Overflow is a well-liked web site the place programmers can ask questions on coding. We recorded the variety of questions tagged to every program throughout the final week previous to our search (June–July 2023). For the Mathematica/Wolfram language, we relied on the sister “Stack” for the Mathematica platform and tallied the variety of programming-related questions requested previously week. These knowledge have been gathered manually. This measure signifies what programming languages are at the moment trending.
IEEE Xplore Digital Library
IEEE maintains a digital library with thousands and thousands of convention and journal articles overlaying a wide selection of scientific and engineering disciplines. We looked for articles that point out every of the languages within the template “X programming” for the years 2022 and 2023, as a result of that is the smallest timeframe for which we might entry articles. For search outcomes that returned hundreds of articles, we recognized the proper pattern measurement for a 95 % confidence interval (often a bit of over 300) and pulled that variety of articles. For every language we sampled, we recognized the share of articles that make the most of the programming language after which multiplied the whole variety of articles by this share to tally the doubtless complete variety of articles that reference a given programming language. We carried out this search in June 2023. This metric captures the prevalence of the completely different programming languages as used and referenced in engineering scholarship.
IEEE Job Site
We measured the demand for various programming languages in job postings on the IEEE Job Site. For search outcomes that returned hundreds of listings, we recognized the proper pattern measurement for a 95 % confidence interval (often round 300 outcomes) and pulled that variety of job listings to manually look at. For every language we sampled, we recognized the share of listings that make the most of the programming language after which multiplied the whole variety of job listings by this share to tally the doubtless complete variety of job listings that reference a given programming language. Additionally, as a result of among the languages we monitor might be ambiguous in plain textual content—resembling lD, Go, J, Ada, and R—we looked for job postings with these phrases within the job description after which manually examined the outcomes, once more sampling entries if the variety of outcomes was giant. The search was carried out in July 2023. We just like the IEEE Job Site for its giant variety of non-U.S. listings, making it a perfect to measure international reputation.
CareerBuilder
We measured the demand for various programming languages on the CareerBuilder job web site. We looked for “Developer” jobs provided throughout the United States, as that is the preferred job title for programmers. We sampled 400 job adverts and manually examined them to establish which languages employers talked about within the postings. The search was carried out in July 2023. We just like the profession builder web site to establish the recognition of programmer jobs within the United States.
GitHub
GitHub is a public repository for a lot of volunteer-driven open-source software program initiatives. We used knowledge gathered by GitHut 2.0, which measures the highest 50 languages utilized by the variety of repositories tagged with that language and attracts from GitHub’s public API. We use two metrics from GitHub: repositories which were “starred” by customers to replicate long-term pursuits, and the variety of pull requests to point present exercise. The knowledge cowl the second quarter of 2023. These measures point out what languages coders select to work in after they have a private alternative.
Trinity College Dublin Library
The library of Trinity College Dublin is certainly one of six authorized deposit libraries in Ireland and the United Kingdom. A replica should be deposited with the library of any ebook revealed or distributed in Ireland, and on request any U.Ok. writer or distributor should additionally deposit a ebook. We looked for all books revealed within the yr so far that had their material categorized as pc programming and totaled the variety of returns. The search was carried out in June 2023. We like this library assortment as a result of it represents a big and categorized pattern of works, primarily within the English language.
Discord
Discord is in style chat-room platform the place many programmers change info. We counted the variety of tags that correspond to every language. In the case of languages that may be names of nonprogramming matters, (many nonprogramming-related matters even have devoted Discord servers; for instance, “Julia” might check with the programming language or the Sesame Street puppet), outcomes have been manually examined. Disboard was searched in June 2023. Disboard lists many public discord servers and plenty of younger coders use the location, contributing a unique demographic of coders.
