The TIOBE Programming Community Index is a leaderboard of programming languages ranked by TIOBE’s points system for the popularity of each language. The index is updated once a month.

Legacy programming languages, once thought to be relics of the past, are having a surprising comeback. This month, Fortran, Ada, COBOL, and Delphi all vying for positions in the TIOBE Index top 20.

Rust, a systems programming language that deals with memory safety flaws, is now in 26th position, ahead of MIT's Julia, and Kotlin, a language endorsed by Google for Android app development.
