Other than generating normal JSON content (stringify), JSON string is used for Javascript string expressions as well.

To create a properly encoded Javascript string, the shortest way is

JSONValue("this'\\is//the\"text").toString();

Yes, it works, but it is uncomfortable to write the code as above. Two issues:

1. It creates a struct, and there are extra processing in the background (check the source code for this.)

2. It is really long.

std.json already has a string encoding function in it, but it is not exposed outside.

It would be quite useful to expose this function for ease of use. Any thoughts?

I've been using http://code.dlang.org/packages/std_data_json instead, and it's in the running to be a replacement for std.json (though I don't know quite what the status of all that it is; it was reviewed but still had work it needed IIRC). It's worked well enough for me and might do better for you than std.json. I don't know though. I pretty much only use JSON when I have to.
