Replacing data fields with code in JSON.stringify?

So you can replace a property with a number, string, array, or object in JSON.stringify, like so:

var myObj = {
    'allstar': aFunction;
}

function myReplacer(key, value) {
    if(key === 'allstar') {
        return 'newFunction()';
    }
}
JSON.stringify(myObj, myReplacer); //returns '{"allstar": "newFunction()"}'

But can you change it so that it instead returns '{"allstar": newFunction()}' (without the quotes around newFunction)?

Solution

  • @derpirscher provided a very good answer that will probably get more upvotes than this one, but this is my preferred answer:

    Based on derpirscher's answer I decided it would be easier to make my own version of JSON.stringify that allows you to replace properties with your own source code, and changed the name of the module so that there is no naming conflict with JSON.
