The top ten are
The Top 10 was effectively static. C++ and Ruby jumped each one spot to split fifth place with C#, but that minimal distinction reflects the lack of movement of the rest of the “Tier 1,” or top grouping of languages.
In fact rather than Swift, Red Monk predicts that Go is doing the best. Six months ago it was predicted that it would become a Top 20 language within six to twelve months. Six months following that, Go can consider that mission accomplished. Go jumped over Visual Basic, Clojure and Groovyand displaces Coffeescript entirely – to take number 17 on the list.
Red Monk said that Julia and Rust are the two notable languages to watch, Julia and Rust’s growth has typically been in lockstep, though not for any particular functional reason. This time Rust outpaced Julia, jumping eight spots to 50 against Julia’s more steady progression from 57 to 56.
