I agree with your perspective on the TIOBE index. It certainly does not offer a perfect representation of popularity, primarily relying on the number of specific online tutorial searches and not accounting for all the factors that could indicate a language's actual popularity. You're spot on about the JavaScript ecosystem. It's vast and has a myriad of libraries, frameworks, and specialized terms that might not be captured by the TIOBE index's algorithms. The significance of JavaScript in web development is undeniable, and it's almost inevitable to learn this language for any web developer. That said, although the TIOBE index has its limitations, it still provides a kind of barometer to understand general trends in the programming world. It's best used in conjunction with other indicators to gain a more comprehensive and balanced view of programming language popularity.
