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);
