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 #13.] Python remains No. 1, followed by C, C++, Java, C#, and JavaScript, while Rust holds its No.
