Part of the problem is that their methodology is based heavily on performing web searches for the phrase "$LANGUAGE programming".
Lots of developers use Javascript in the course of their work. Few of them will refer to their work as "Javascript programming" -- they will typically use either a broader term, like "web development", or a more specific one, like "React development". Neither of these would influence TIOBE's rankings.
