Perl skilled a slight decline within the TIOBE Programming Group Index rankings between August and September, falling one place to ninth within the high ten. Nevertheless, Perl stays considerably extra fashionable this yr than it was final yr, so its rising trajectory continues to be notable. Perl sits at 2.03% in TIOBE’s proprietary rating system in September, up from 0.64% in January. Final yr, Perl held the twenty seventh place.
The TIOBE Index is an indicator of which programming languages are hottest inside a given month. Every month, we study the patterns and adjustments within the index, notably the highest ten.
Prime 10 programming languages in September 2025
In accordance with the TIOBE Programming Group index, the next are the highest 10 programming languages in September 2025.
- Python: A general-purpose programming language generally used for back-end growth and information science. programming language for learners.
- C++: Similar to C, with the addition of courses and objects. C++ is well-suited for recreation and system growth. It might be comparatively tough to study.
- C: A programming language typically utilized in app and system growth. Its syntax is just like different fashionable languages, making it a helpful branching-off level for newbie builders.
- Java: An exceptionally good language for AI, app, and net growth. Java requires comparatively superior expertise to study.
- C#: Utilized in app, recreation, and net growth, C# is an object- and component-oriented programming language just like the C and Java language households.
- JavaScript: A scripting language typically used for app, recreation, and net growth in addition to net servers. JavaScript is less complicated and extra versatile than Java, which makes it inappropriate for some programming duties however typically simpler to study.
- Visible Fundamental: A programming language with a drag-and-drop consumer interface that’s helpful for front-end and full-stack growth. Visible Fundamental is designed to be simple to make use of.
- Go: A comparatively easy-to-learn language appropriate for back-end growth and dealing with APIs and net companies.
- Delphi/Object Pascal: Object Pascal is an object-oriented programming language spun out of the Pascal language by Apple builders and infrequently used with the Delphi compiler. Object Pascal is designed to be simple to make use of and study, so long as it’s realized in reference to the Delphi compiler.
- Perl: Perl is a general-purpose language first launched in 1987. It may well perform as a “glue” between techniques not initially made to interoperate and for producing SQL queries, amongst many different makes use of. It’s usually thought of simple to study.

What’s the TIOBE Index?
The TIOBE Index’s proprietor, TIOBE Software program CEO Paul Jansen, notes the index just isn’t a prize for the “finest” language or a listing of wherein programming language probably the most code has been written; as an alternative, he makes use of fashionable engines like google to find out which languages are most used amongst skilled programmers, programming programs, and third-party distributors.
