import std.json;

    void main() {
        JSONValue j = ["a": "b", "x": "y"];
        //j.remove("x");
        //j["x"] = null;
        destroy(j["x"]);
    }

What's the proper way to delete a node from a JSONValue object?

I was looking for something like remove("x") that you can do with an associative array, but std.json doesn't provide that. Setting the node to null or using destroy doesn't actually remove the node so that it's not serialized when using toJSON().

Here the right way:
j.object.remove("x");

I found std.json syntax a bit strange, so I wrote a wrap over std.json to add a bit of syntax sugar:

Thanks. That does the trick.

Thanks. I'll check it out.
