Как удалить из JSOn по атрибуту?

var myjson = [{
		"name": "Mike",
		"incentives": "23.45"
	},
	{
		"name": "Larsen",
		"incentives": "34.78",
		"newlyadded": true
	},
	{
		"name": "Steve",
		"incentives": "26.78"
	}
];

myjson = myjson.filter((obj) => typeof obj.newlyadded === 'undefined' || obj.newlyadded !== true);

console.info(JSON.stringify(myjson))

$(document).ready(function() {
 
 
 var myjson = [{
		"name": "Mike",
		"incentives": "23.45"
	},
	{
		"name": "Larsen",
		"incentives": "34.78",
		"newlyadded": true
	},
	{
		"name": "Steve",
		"incentives": "26.78"
	}
];



json = myjson.filter((obj) => obj.hasOwnProperty('newlyadded') === false);

console.info(JSON.stringify(json))
 
});
