JSON5 - like JSON but for human-editing

So JSON was originally made for machines. But what if you like JavaScript syntax and don't feel like maintaining meta files for your project in a different format (e.g. YAML)?

Enter JSON5: https://github.com/aseemk/json5

Killer feature: comments inside files are allowed!
Very handy for maintaining external configuration files.

Among other features, object keys don't need to be quoted and strings can be single-quoted. So far not a big change over JSON but much easier to write by hand!
