While the company's ranking of programming languages is influential among developers, O'Grady notes that numerical rankings should be "taken with a grain of salt". The company produces the ranking twice a year.
Python has been rising across several programming language popularity indexes, including Tiobe and IEEE Spectrum.
Rust is a popular language among developers who discuss technical challenges on StackOverflow, but it hasn't moved from its spot at 21. As O'Grady notes, Rust has the potential for core infrastructure projects but, like Google-created Go, it seems to be stuck on its current ranking. Go meanwhile has risen one place to 14.
Python rival, R, a popular language for data scientists and academics, has gained two places and is now at 13th spot, which O'Grady reckons is about as high as it will ever get. On the other hand, Python's rise in data analytics hasn't impacted R's ranking over time.
"Given the language's specialized focus, this is likely its effective ceiling, but it's also an illustration of the remarkable popularity of a language whose usage is restricted for all intents and purposes to a single domain – those who work with and operate on data," he noted.
Kotlin, a popular language among Android developers, has gained one spot and is now at 19th.
A recent survey by Snyk of developers who use JVM-compatible languages found that more developers are turning to Kotlin due to its neat integration with Java. More developers now use it than Clojure and Scala. But RedMonk ranks Scala at 13th place.
Google-created Dart has also risen three places, which appears to align with the rise in popularity of the Flutter UI toolkit, which is also developed by Google. In GitHub's 2019 State of the Octoverse report, Dart and Flutter ranked first and second for fastest-growing language and open-source project, respectively, over the past 12 months.
RedMonk placed Dart in 33rd spot 18 months ago and since then it's risen to 24th position.
