If is posible add function to conver all object to array?

[root9]

I got a lot [object Object],[object Object],[object Object],[object Object] in log on server.

I try some thing to use JSON.stringify but I have Circular reference problem so I write some code like this, maybe you can add to this addon if you like :)

This code maybe need to rewite to work better

var products = [
   {id:102, price:200.3}, 
   {id:3, price:104.5},
   {id:10, price:20},
   [
       {id:102, price:200.3}, 
       {id:3, price:104.5},
       {id:10, price:20},
       [
           {id:102, price:200.3}, 
           {id:3, price:104.5},
           {id:10, price:20},
       ]
   ]
];

function convert2array(obj, properties, deep, maxdeep) {
    ++deep;
    for(var key in obj) {
        if(obj.hasOwnProperty(key) && typeof obj[key] !== 'function') {
            if (deep < maxdeep) { 
                if (obj[key] != null && typeof obj[key]  === "object") {
                    if (obj[key].length > 0) {
                        properties[key] = [];
                        convert2array(obj[key], properties[key], deep, maxdeep);
                    }
                } else if (typeof obj[key]  === "number" || typeof obj[key]  === "string" || typeof obj[key]  === "boolean") {
                    properties.push(key + ': ' + obj[key]);
                } else {
//                    console.log('error: ' + key, obj[key]);
                }
            }
        }
    }

    return properties;
}

var cache = [];
var properties = [];
JSON.stringify(products, function(key, value) {
    if (typeof value === 'object' && value !== null) {
        if (cache.indexOf(value) !== -1) {
            // Circular reference found, discard key
            return;
        }
        if (typeof value  === "object" && value != null) {
            var res = convert2array(value, properties, -1, 4);
            properties.push(key + ': ' + res);
            cache.push(value);
        } else if (typeof value  === "number" || typeof value  === "string") {
            properties.push(key + ': ' + value);
            cache.push(value);
        }
    }
    return value;
});

console.log(properties);
