This is a silly comment, and missing content that would make it helpful. At least say why you think these things are better than C. They want a language that allows them to explore the depths of systems, so they may very well want C or similar.

Please try to be more helpful and less presumptive, especially when someone is asking to learn.

They're not trying to explore the "depths of the system". They're tired of the many layers of transformation and build steps in web dev.

Those are kind of unavoidable if you want to package your code for multiple browsers, but with the languages above, you at least only have a single build step from your code to a deployable web package, and you can get much closer to the metal (e.g. write your own server) without having to manually manage memory.
