Programming Language Popularity Increases for R, Julia, and Rust (but Not Go)
TechRepublic reports: The TIOBE Index is a monthly indicator of programming-language popularity based on factors including skilled engineers, courses, and third-party vendors. The October 2026 rankings show a largely stable top 10, with R overtaking SQL and Julia returning to the top 20 for the first time in three years. [SQL has risen to #9 from #10 in October of 2025 — back when R ranked only…
The TIOBE Index, a monthly indicator of programming language popularity, reveals a mostly stable top 10 in October 2026. Python maintains its position at No. 1, while C, C++, Java, C#, and JavaScript follow. Julia reenters the top 20 for the first time in three years, climbing from No. 21 to No. 18. R surpasses SQL and now ranks higher than it did last October, when it was at No. 13.
Rust remains at No. 10, and Dart and OCaml make notable strides, jumping from positions 41 and 38 to 27 and 26, respectively. Go, however, drops from No. 8 to No. 11, while Delphi/Object Pascal falls from No. 9 to No. 19. Julia's growing popularity is attributed to the need for modern programming languages that offer high performance and ease of learning, particularly for numerical computing.
