If you're making comments for yourself in config files you control:

/\/\/.*/gm

"hello // syntax error"

You are 100% correct. For not single line comments, "//" in the datastructure, and everything else there are already well tested solutions for the problem. https://github.com/sindresorhus/strip-json-comments

My point is only that this isn't a big issue. I don't understand why so many see it as a large issue. Instead, projects use non-standard YAML or other problematic solutions only because "JSON doesn't have comments".
