If you hire, what stands out to you more: vanilla js or framework projects?
Depends what is being hired for. Note that [in general] a hiring dev is very unlikely to look through the codebase of any of your projects in any great detail (not much beyond a possible cursory look at a few files) unless they have a very specific reason for doing so. It’s also extremely unlikely that they’ll run any code, so just making everything live and polished is more important. When hiring for a junior position they need a very quick assesment of whether you understand the basics (do these things look good, do they seem to work, is there some evidence of knowledge of basic concepts like HTTP, AJAX etc etc). Whether you’ve used a framework of or not is likely to be of minimal importance (but obviously it’s all context-dependent).
