The author says he would ignore a nice looking resume for c++ developers but not frontend developers. This is only because he's consciously aware of it.

When I used to look for jobs, I was one of the only to use LaTeX and it was most definitely a point of discussion when I was called in.

Sadly the LaTeX resume templates now look like something out of MS Word.

So whether or not you're a frontend Dev, every non cringy thing you can do to stand out is important.
