Ask HN: Fullstack or front-end for first dev job?

I'm an ex-Product Manager trying to break in to software development. I've spent the last few months learning Javascript and React. I'm by no stretch an expert, but I feel that I have a firm foundation.

I intended to learn back-end development before applying for jobs, but I've heard that nobody hires junior full stack developers.

Is this true in your experience? Should I learn any back-end, just get really good at React, or learn some other web technology? Any other advice re: getting my first dev job would be hugely appreciated.

Thanks in advance!
