Fortran Returns to the TIOBE Top 10: History, Features, and Comparative Analysis

The TIOBE May 2024 index announced that Fortran has re‑entered the Top 10 programming languages, prompting curiosity about the factors behind its resurgence.

Since its inception in 1957, Fortran has undergone continuous evolution, with the latest ISO Fortran 2023 standard demonstrating its ongoing modernization. Its strengths in high‑performance numerical and scientific computing, combined with mature, free, open‑source implementations, give it a cost‑effective edge.

Compared with other languages, Python is popular but slower; MATLAB is user‑friendly but costly; C/C++ are fast but lack native mathematical support; R lags in speed and adoption; Julia shows promise but is still maturing. Fortran’s speed, native math capabilities, maturity, and zero cost allow it to remain competitive.

Fortran’s official website ( https://fortran-lang.org/ ) and Chinese documentation ( https://fortran-lang.org/zh_CN/learn/ ) provide resources. Market interest is evident, as “Fortran programming” searches on Amazon far exceed those for newer languages like Kotlin and Rust.

The language’s origins trace back to IBM’s John Backus team in 1957, designed to simplify scientific computation. Over decades it has progressed through standards such as Fortran IV, 66, 77, 90, 95, 2003, 2008, 2018, and the recent 2023 version, adding parallel computing support from Fortran 90 onward.

Fortran is widely used in scientific computing, engineering simulation, numerical analysis, weather forecasting, and quantum physics, and runs on Windows, Linux, and macOS platforms.

Overall, Fortran’s revival illustrates that classic languages can coexist with modern innovations, maintaining relevance through performance, openness, and continuous development.
