I'm trying to replicate the json stringify method but instead use recursion. I've been able to pass alot of test cases but when it comes to nested arrays I seem to be having issues. if there's any empty array inside an array ('[]'), i get something like [,7,9] instead of [[],7,9]. Also if I pass in: 





 stringifyJSON([[["test","mike",4,["jake"]],3,4]])
 "[[test,mike,4,jake,3,4]]"



I thought I was close in getting this to work, but I might have to start over. Do you guys have any ideas on what I might be able to change to make this work for nested examples? Here's the code I have now:





 var testarray = [9,[[],2,3]] //should return '[9,[[],2,3]]'
 var count = 0
 var stringifyJSON = function(obj,stack) {
 	var typecheck = typeof obj;
 	var resarray = stack;
 	if(resarray == null){	//does resarray exist? Is this the first time through?
 		var resarray = [];
 	}
 	if(typeof obj === "string"){	//Is obj a string?
 		return '"' + String(obj) + '"';
 	}

 	if((Array.isArray(obj)) && (obj.length > 0)){ //If not a string, is it an object?
 		for(var i = 0; i<obj.length;i++){
 			if(Array.isArray(obj[i])){
 				var arraytemp = []
 				stringifyJSON(arraytemp.push(obj[i]),resarray) // this is probably incorrect, this is how i handle a nested array situation
 			}
 			if(typeof obj[i] === 'number'){		//if the number is inside of the array, don't quote it
 				resarray.push(obj[i]);
 			}
 			else if(typecheck === 'object' && Array.isArray(obj[0])){
 				resarray.push('[' + obj[i] + ']');
 			}
 			else{
 				resarray.push('"' + obj[i] + '"');
 			}
 			
 			obj.shift()		//delete the first object in the array and get ready to recurse to get to the second object.
 			stringifyJSON(obj,resarray); //remember the new array when recursing by passing it into the next recursive instance
 		}
 	}

 	if(obj !== null && typeof obj === 'object'){	//is obj an object?
 		for(var key in obj){
 			stringifyJSON(resarray.push(key + '"' + ':' + obj[key]),resarray)
 		}
 		

 	}
 	if(typeof obj === "number" || obj == null || obj === true || obj === false){	//special cases and if it's a number
 		return '' + obj + ''
 	}
 	if(typecheck === 'object'){	//a special case where you have an empty array that needs to be quoted.
 		return '['+resarray+']'
 	}
 	return '' + resarray.join('') + '';

 	

 };

 //JSON values cannot be a function, a date, or undefined
