Have you seen the latest TIOBE rankings report?
The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third-party vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.
It has been stated before, programming language popularity is rather stable. If we look at the first 10 programming languages in the TIOBE index, then C# is the youngest of them all. C# started in 2000. That is 23 years ago! Almost every day a new programming language is born, but hardly any of them enter the top 100. At least not in their first 10 years. The only languages younger than 10 years in the current top 100 are: Swift (#14), Rust (#17), Crystal (#48), Solidity (#59), Pony (#71), Raku (#72), Zig (#88) and Hack (#92). None of them are less than 5 years old. In other words, it is almost impossible to hit the charts as a newbie. On the contrary, we see that golden oldies revive. Take for instance Fortran, which is back in the top 20 thanks to the growing demand for numerical computational power. So, if you have just invented a brand new language, please have some patience! — Paul Jansen CEO TIOBE Software
