Recursive Javascript array display. Nice output.

	function printArray (arr, depth) {
		depth++;
		indentLog("[", depth);
        for (var index in arr) {	
		    if (typeof(arr[index]) == "object") {
		    	if (typeof(arr) == "object")
		    		indentLog(index + "=> Array", depth);
		    	else {
		    		indentLog(arr, depth);
	            	indentLog(index, depth);
		    	}
	            printArray(arr[index], depth);
		    } else {
		    	indentLog(index + "=> " + arr[index], depth);
		    }
	    }
	    indentLog("]", depth);
	}

	function indentLog(msg,space) {
		str = "";
		for (var i = 0; i < (space*2); i++) {
			str += ".";
		}
		str += msg;
		console.log(str);
	}
