Groovy, which came to life in 2007, hasn't been a top-20 language in Tiobe's index since 2016 but in the February listing it is now at 19th place, up from 49th last year.
Groovy hit its stride as a language for writing scripts for popular continuous-integration tool Jenkins, but it's also been buoyed by the Gradle open-source build-automation system. According to Tiobe, these days more 'glue' software is being written in Groovy.
The rankings are based on searches on popular websites including Google, Bing, Yahoo, Wikipedia, Amazon, YouTube, and Baidu.
Microsoft's TypeScript dropped to 57th place this month but Tiobe reckons this is a blip and it should return to the top 50 soon.
The PYPL PopularitY of Programming Language February ranking is also out. It's based on Google searches for language tutorials.
According to PYPL, Python remains the most popular language, but up 5.2 percentage points from last year. It now has a share of 26.42 percent. It's followed by Java, which dipped 1.3 percentage points compared with last year and now has a share of 21.2 percent.
