Rounding out RedMonk's top 10 were Python, C#, C++, Ruby, CSS, C, and Objective-C. In spots 11 to 20 were Perl and Shell (tied for 11th), R, Scala, Haskell, Matlab, Go and Visual Basic (tied for 17th), Clojure and Groovy (tied for 19th).
O'Grady sees trends worth nothing involving several languages, including Go, R, and Swift. "In our last rankings, it was predicted based on its trajectory that Go would become a top 20 language within six to 12 months," he said. "Six months following that, Go can consider that mission accomplished. In this iteration of the rankings, Go leapfrogs Visual Basic, Clojure and Groovy -- and displaces CoffeeScript entirely -- to take number 17 on the list."
R held steady in the 13th spot after four consecutive gains. "Even if R's [growth] does stall at 13, however, it will remain the most popular statistical language by this measure," said O'Grady, "and this in spite of substantial competition from general purpose alternatives like Python."
O'Grady sees Swift, Apple's new language introduced last year, as a "curious" case, jumping from 68th in the last rankings to 22nd now. "From its position far down on the board, Swift now finds itself one spot behind CoffeeScript and just ahead of Lua," he said. "Given this dramatic ascension, it seems reasonable to expect that the Q3 rankings this year will see Swift as a Top 20 language."
