Perl experienced a slight decrease in the index classifications of the Tiobe programming community between August and September, falling a ninth place in the top ten. However, Perl is still significantly more popular this year than last year, so his ascending career remains remarkable. Perl is 2.03% in the Tiobe patented classification system in September, compared to 0.64% in January. Last year, Perl took place 27.
The Tiobe index is an indicator of which programming languages are more popular in a certain month. Every month, we examine the patterns and changes in the index, particularly the best ten.
Top 10 programming languages in September 2025
According to him Tiobe programming community indexThe following are the 10 best programming languages in September 2025.
- Piton: A generally used generally used programming language for the development of Back-End and data science. A good programming language for beginners.
- C ++: Very similar to C, with the addition of classes and objects. C ++ is suitable for the development of games and systems. It can be relatively difficult to learn.
- DO: A programming language often used in the development of applications and systems. Its syntax is similar to other popular languages, so it is a useful branch point for beginner developers.
- Java: An exceptionally good language for AI, application and web development. Java requires relatively advanced skills to learn.
- DO#: Used in the development of applications, games and web, C# is a programming language oriented to objects and components similar to language families C and Java.
- JavaScript: A command of command sequences often used for the development of applications, games and web, as well as web servers. JavaScript is simpler and more flexible than Java, which makes it inappropriate for some programming tasks, but is often easier to learn.
- Visual Basic: A programming language with a drag and release user interface that is useful for front and complete development. Visual Basic is designed to be easy to use.
- Go: A relatively easy to learn language for the development of Back-End and work with API and web services.
- Delphi/Object Pascal: Object Pascal is an object -oriented programming language out of the Pascal language by Apple developers, it is often used with Delphi’s compiler. Object Pascal is designed to be easy to use and learn, provided you learn in relation to the Delphi compiler.
- Perl: Perl is a general purpose language launched for the first time in 1987. It can function as a “glue” between the systems that are not originally performed to interoperate and generate SQL consultations, among many other uses. It is usually considered easy to learn.
Notable movements in the list of the 10 best in September

Python’s unstoppable increase fell slightly 26.14% in August to 25.98% in September. Python is still far ahead of any other language in the index.
In another part of the Tiobe index classification table, Delphi/Object Pascal changed with Perl to win the ninth place. Delphi/Object Pascal grew from 1.82% in August to 2.26% in September. At number 11 and 1.86%, SQL is quite close to entering Top 10 again.

What is the Tiobe index?
The owner of the Tiobe Index, the CEO of Tiobe Software, Paul Jansen, points out that the index is not a prize for “better” language or a list in which the largest amount of programming code has been written; Instead, use popular search engines to determine which languages are used more among professional programmers, programming courses and third -party suppliers.
Threat actors compromised NPM packages (node package administrator) with malware that can steal cryptocurrencies.
