JavaScript: like JSON.stringify but handles functions, good for creating arbitrary .js objects?
var stringify = function(obj, prop) {
var placeholder = '____PLACEHOLDER____';
var fns = [];
var json = JSON.stringify(obj, function(key, value) {
if (typeof value === 'function') {
fns.push(value);
return placeholder;
}
return value;
}, 2);
json = json.replace(new RegExp('"' + placeholder + '"', 'g'), function(_) {
return fns.shift();
});
return 'this["' + prop + '"] = ' + json + ';';
};
var foo = {
a: function() { return 'a'; },
b: function() { return 'b'; },
'bar.baz': {
'omg ponies!!': function() { return 'c'; }
}
};
console.log(stringify(foo, 'foo'));
// this["foo"] = {
// "a": function () { return 'a'; },
// "b": function () { return 'b'; },
// "bar.baz": {
// "omg ponies!!": function () { return 'c'; }
// }
// };

how cool, if you can get to the solution to your current problem with function, share

^^handles concise method syntax and fat arrows.

This stringify function is a custom implementation designed to stringify JavaScript objects, similar to JSON.stringify, but with the ability to handle functions within the object. It replaces slice master functions with a placeholder string during the stringification process and then restores them after the JSON string is created.

Just wanted to comment that this function has saved me more than once!

the link is dead, but your code was enough for me now.
